What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Table is shown in figure.

Two points on the table are (3, 0) and (4, 1).

Now,

Since, The equation of function passes through the points,

(3, 0) and (4, 1).

So, We need to find the slope of the function.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 0) / (4 - 3)

m = 1

Thus, The equation of function with slope 1 is,

⇒ y - 0 = 1 (x - 3)

⇒ y = x - 3

⇒ y = x - 3

Thus, The equation of function notation for the relation will be,

⇒ y = x - 3

all of the following are true

Answer:Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).

Step-by-step explanation:

Answer:

For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.

For the question, all of the numbers equal the ration 5:3.

Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.

Step-by-step explanation:

1A:

2.5 amount of water  - 1.5 amount of pasta

10 amount water - 6 amount pasta

15 amount water - 9 amount pasta

2.5 : 1.5

5 : 3

10 : 6

15 : 9

1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.

2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.

The zero of a function is where the answer is zero, so x=0 there. There's one point on this graph that has a point where x=0, and that is at y=1. Hope this helped :)

Answer: Length = 12 units

Width = 6 units

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice its width, thus means that the length will be: = 2x

Perimeter of a rectangle = 2(l + w)

where,

L = length

W = width

Therefore,

Perimeter = 2(l + b)

36 = 2(2x + x)

36 = 2(3x)

36 = 6x

x = 36/6

x = 6

Width = 6 units

Length = 2 × Width = 2 × 6 = 12 units

Exterior Angle Property of a Triangle

Step-by-step explanation:

According to exterior angle property of a triangle , the measure of any one exterior angle of a triangle is equal to the the sum of measure of it's opposite interior angles.

The relationship between angles 1, 2 and 3 is that they follows exterior angle principle. Therefore, ∠3 = ∠2 + ∠1

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

In other word, the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles

Therefore, the angle 3 is related to angle 1 and 2(remote interior angles) by the exterior angles theorem. Mathematically, this can be represented as follows:

∠3 = ∠2 + ∠1

Answer:

Yes, they can both be solved and get the same answer.

Step-by-step explanation:

Tyler's way:

Since Tyler solved first by isolating x, resulting in x=-5-3y, he can then go and look at the second equation and solve for y there. In the second equation you're going to want to subtract 9x from the right side and left side to then get 3y=3-9x. Now you're going to divide by 3 on both sides to isolate y. You'll get y=1-3x. Now we know what y equals. Plug that back into the first equation and you'll get x=-5-3(1-3x). Use the distributive property to simplify that and you'll get x=-5-3+9x. That simplified is x=-8+9x. Add 8 on both sides and you'll get 8+x=9x. Subtract x from the both sides and you'll get 8=8x. Divide by 8 on both sides and you'll get the final answer: 1=x, or x=1.

Han's way:

Since Han solved first by isolating 3y, resulting in 3y=-5-x, he can then go and look at the second equation and solve for y there. In the second equation you're going to want to subtract 9x from the right side and left side to then get 3y=3-9x. Now you're going to divide by 3 on both sides to isolate y. You'll get y=1-3x. Now we know what y equals. Plug that back into the first equation and you'll get 3(1-3x)=-5-x. Use the distributive property to simplify that and you'll get 3-9x=-5-x. Add 9x to both sides and you'll get 3=-5+8x. Add 5 to both sides to isolate 8x and you'll get 8=8x. Divide by 8 on both sides and you'll get the final answer: 1=x, or x=1.

Determine if both first steps can be used to solve the system and will yield the same solution

Both Tyler and Han's first step can be used to solve the system and will yield the same solution

Given:

x + 3y = -5

x + 3y = -5 9x + 3y = 3

Tyler

isolate x in the first equation to get

x = -5 - 3y

substitute into second equation

9x + 3y = 3

9( -5 - 3y) + 3y = 3

-45 - 27y + 3y = 3

- 24y = 3 + 45

-24y = 48

y = 48/-24

y = -2

Recall,

x = -5 - 3y

= -5 - 3(-2)

= -5 + 6

x = 1

Han:

isolate 3y in the first equation to get

3y = - 5 - x

substitute into second equation

9x + 3y = 3

9x + (-5 - x) = 3

9x -5 - x = 3

8x = 3 + 5

8x = 8

x = 1

Recall,

3y = - 5 - x

3y = -5 - (1)

3y = -5 - 1

3y = - 6

y = -2

Therefore, both first steps can be used to solve the system and will yield the same solution.
