Answer:
Slope = 3
Step-by-step explanation:
The slope is the Rise/Run
Given the two points (-1,-4) and (2,5) we can calculate both the Rise and the Run:
Rise = (5 - (-4)) = 9
Run = (2 - (-1)) = 3
Slope is Rise/Run
(9/30) = 3
It is the "m" in y = mx + b
The actual equation is y = 3x + 1. Use one of the 2 points and solve for b to find that it equals -1.
y = 3x - 1 for (2,5)
5 = 3(2) - 1 ?
5 = 5 Yes
