Question

Write an equation for the function that includes the points (-2, 3) and (-1, 9)

Answer 1

y=6x+15

Explanation:

(-2,3) (-1,9)=9-3/-1+2=6/1 or 6

this happens because the slope goes in a form of rise over run

I found the y-intercept by continuing the pattern as the y-axis go up by 6 the x-axis go up by 1 and finish until x is 0 and y is another number.

Answer 2

The answer to your question is m = 6

Explanation:

Data

A = (-2, 3)

B = (-1, 9)

Process

1.- Write the formula to calculate the slope

slope = m = (y2 - y1) / (x2 - x1)

2.- Identify the values of x1, y1, x2 and y2

x1 = -2 y1 = 3 x2 = -1 y2 = 9

3.- Substitution

m = (9 - 3) / (-1 + 2)

4.- Simplification

m = 6 / 1

5.- Result

m = 6
