What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1)

Answers

Step-by-step explanation:

Hey there!

Note: Use double point formula for finding the eqaution which passes through two points.

Given;

The points are; (1,-3) and (3,1).

Use double point formula.

[tex](y - y1) = \frac{y2 - y1}{x2 - x2} (y - y1)[/tex]

Put all values.

[tex](y + 3) = \frac{1 + 3}{3 - 1} (x - 1)[/tex]

Simplify it.

[tex](y + 3) = \frac{4}{2} (x - 1)[/tex]

[tex]y + 3 = 2(x - 1)[/tex]

[tex]y + 3 = 2x - 2[/tex]

[tex]y = 2x - 2 - 3[/tex]

[tex]y = 2x - 5[/tex]

Therefore, the eqaution is y = 2x-5.

Alternative:

Steps:

Find slope using slope formula and use one point formula.Simplify in the form of y = mx+c form.

Formula:

Slope = (y2-y1)/(x2-x1)One point formula= (y-y1)= m(x-x1)

The points are; (1,-3) and (3,1).

Now;

Slope= (1- (-3))/(3-1)

= (1+3)/2

= 2

Again;

Using one-point formula.

(y+3) = 2(x-1)

y+3= 2x-2

y = 2x -5

Therefore, the equation is y = 2x-5.

The graph shows the savings in Andre’s bank account.

Answers

Answer:

As the number of week increases, the Andre's savings also increases

Step-by-step explanation:

Given

The attached graph

Required

Explain what the slope represents (Missing part of the question:)

First, we'll check the slope of the graph.

Represent time in weeks with x and savings in dollar with y

So, we have the following details:

[tex](x_1,y_1) = (0,40)[/tex]

[tex](x_2,y_2) = (8,80)[/tex]

Slope (m) is then calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{80 - 40}{8 - 0}[/tex]

[tex]m = \frac{40}{8}[/tex]

[tex]m = 5[/tex]

The calculated slope is positive and this implies that: As the number of week increases, the Andre's savings also increases

Answer:

answer is 45 add all angle=360 it make 360/8

Answer:

x = 45

Step-by-step explanation:

The 2 interior angles of the triangle adjacent to both 3x's is

180 - 3x

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2x is an exterior angle of the triangle, thus

180 - 3x + 180 - 3x = 2x , that is

360 - 6x = 2x ( add 6x to both sides )

360 = 8x ( divide both sides by 8 )

45 = x

The sum of the interior angle of a triangle is equal to the exterior. . The value of x from the given figure is 3

Angles in a triangle

The sum of the interior angle of a triangle is equal to the exterior. According to the given figure;

25x + 57 +x = 45x

26x + 57 = 45x

Subtract 57 from both sides

26x -45x = -57

-19x = 57

x = 57/19

x = 3

Hence the value of x from the given figure is 3

how high did zane climb every 7 seconds

A 7/5 meters

B 5 meters

C 5/7 meters

D 7 meters

Answers

Answer:

Step-by-step explanation:

Zanes can climb 5/7 meters for every 7 seconds.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

This is clearly shown in the graph of Zane's elevation relative to the rim of the volcano in meters as a function of time in seconds.

The graph showed that Zane was climbing the volcano at a constant rate, creating a linear graph of his movement.

From the graphical representation, it could be seen from the graph that the x-intercept is (0,5) and the y-intercept is (7,0)

Slope of line is m=5/7

Hence, Zanes can climb 5/7 meters for every 7 seconds.

Answer:

Answer: SAS

Step-by-step explanation:

We must prove that triangles ABC and EDC are congruent.

Since BD bisects AE, then AC is congruent with CE.

Since AE bisects BD, then BC is congruent with CD

Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.

Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.
