Answer:
a = -5/3
Step-by-step explanation:
3/a × -4 = 20
3a × -4/-4 = 20/-4
3a = -5
a = -5/3
Check:
3/(-5/3) × - 4 = 20
-5 × - 4 = 20
Answer:
y = -3x + 8
Step-by-step explanation:
First, find the slope of the equation.
delta y/ delta x = (-4-11)/(4-(-1)) --> -15/5
The slope is -3
y = -3x + b
To find b, input the values of one of the ordered pairs
Using (4,-4) :
-4 = -3(4) + b
-4 = -12 + b
8 = b
The final equation is y = -3x + 8
