Answer:
y = 8/5x – 3
Step-by-step explanation:
First, find the slope using rise over run (y2 – y1) / (x2 – x1)
(y2 – y1) / (x2 – x1)
(-19 – 5) / (-10 – 5)
-24 / -15
= 8/5
Plug in the slope and a given point into y = mx + b, and solve for b
y = mx + b
5 = 8/5(5) + b
5 = 8 + b
-3 = b
Plug in the slope and b into y = mx + b
y = 8/5x – 3
So, the equation is y = 8/5x – 3
