Question

Write the slope-intercept equation for the line that passes through (-1, -4) and (4, 11)

Answer 1

Slope is 3.

Answer 2

11 - (-4)/ 4 - (-1) = 15/5 = 3

Answer 3

Now pick either point:
11 = 3(4) + b
11 = 12 + b
-1 = b
So, y = 3x -1 is your answer.

Answer 4

Note: I used y = mx + b, and plug in 11 for y, 3 for m and 4 for x.
