Question

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

Answer 1

Answer:

The answer to your question is  m = 6

Step-by-step 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

Answer 2

Answer:

y=6x+15

Step-by-step 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.
