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.

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

Answers

Answer:

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

What is h(x) = f(x)g(x)?

h(x) = 24x2 – 14
h(x) = 24x2 + 40x + 14
h(x) = 24x2 + 16x – 14
h(x) = 24x2 + 12x – 14

h(x) = (6x + 7)(4x - 2)

If  two lengths of a triangle are 14 and 17. Then the largest possible whole number perimeter is 62.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two lengths of a triangle are 14 and 17.

Side one is fourteen and side two is seventeen.

First we need to find the largest third side

The third side should always be less than the sum of other two sides lengths.

14+17

31

The third side must be less than 31, the largest possible third side is 30

Now let us find the perimeter of triangle.

Perimeter=14+17+31

=62

Hence the largest possible whole number perimeter is 62.
