Answer:

y = x + 1

Step-by-step explanation:

(2,3)  (-2, -1)

line equation y - y1 = m (x - x1)

m = (-1 -3) / (-2 - 2)

= -4 / -4 = 1

y - 3 = 1 * (x - 2)

y = x -2 +3

y = x + 1

Answer:

y = 1x+1

Step-by-step explanation:

Slope-intercept form is: y=mx+b

In order to find the slope, or "m" in this formula with two given points, use the slope formula for two coordinates: m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].  In this formula, y2 is the second coordinate's y value, y1 is the first coordinate's y-value, and likewise x2 is the second coordinate's x value, x1 is the first coordinate's x-value.

In this problem specifically, we were given coordinates (2,3) and (-2,-1).

This is how those above values would line up:

y2 = -1

x2 = -2

y1 = 3

x1 = 2

Once this is plugged into the formula it becomes [tex]\frac{-1-3}{-2-2}[/tex] , which simplifies to a slope (m) of 1.  

____________________________________________________________

Next to find the y-intercept, or "b" we simply need to plug in a coordinate's values into the slope-intercept form, and I chose (2,3) for simplicity's sake.

This would become (3) = 1(2) + b. Then just solve for b using algebra, which results in a b value of 1.  

The answer is y= 1x +1 which can alternatively be written as y=x+1

Answer:

Step-by-step explanation:

When y=2, you just plug in the number 2 every time y appears in the equation.

Therefore, [tex]6*(2)*3-19+9*(2)*2+(24/6)...\\[/tex]

Now that can be simplified by just multiplying/dividing out each term as needed

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

a)

The hair length is about 8 cm

b)

It takes about 18 months.

c)

it takes about 40 months.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The coordinates from the graph:

(2, 1), (3, 1.5), (4, 2), (6, 3), and (8, 4)

Where the x-axis is the number of months and the y-axis is the length of the hair in inches.

Now,

1 inch = 2.54 cm

3 inches = 3 x 2.54 = 7.62 cm
The hair length after 6 months.

= (6, 3)

= 3 inches

= 7.62 cm

Now,

6 months = 3 inches

Multiply 8/3 on both sides.

8/3 x 6 months = 8 inches

16 months = 8 inches

Now,

From the graph, we see that,

(8, 4)

This means,

In 4 months the length of the hair is 4 inches.

8 months = 4 inches

Multiply 5 on both sides.

40 months = 20 inches

Thus,

a)

The hair length is about 8 cm

b)

It takes about 18 months.

c)

it takes about 40 months.

Answer: 1, There is no correlation between outside temperature and number of appointments made.

Step-by-step explanation: It would be 1 because in the problem it states that even though temperatures were lower outside, their number of appointments had not changed. Because the number of appointments had not changed, there is no correlation between the temperature outside and number of appointments made.

The difference of the given expression is 5x/12 - 5.

The given expressions are (3/4 x-1) and (1/3 x+4).

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Here, (3/4 x-1) - (1/3 x+4)

= 3/4 x -1 -1/3 x -4

= (3/4 x - 1/3 x) -1-4

= 9/12 x - 4/12 x) - 5

= (9-4)/12 x - 5

= 5x/12 - 5

Therefore, the difference of the given expression is 5x/12 - 5.
