Answer:
y = -2x + 19
Step-by-step explanation:
Firstly, you need to do y = mx + b
Your y is going to be from the given y coordinate (3) , the m will be the slope (-2), and the x will be the from the given x coordinate (-8).
3 = -2(-8) + b Write out equation
3 = -16 + b Simplify
+16 = +16 + b Add 16 to both sides
__________
19 = b Now you have b
y = -2x + 19
-2x is your slope and +19 is your b
