Answer:

Step-by-step explanation:


X = -4 – -2 = -2
Y = 4 – 10 = -6

Equation of the line:
y = 3x + 16
When x=0, y = 16
When y=0, x = -5.3333333333333
4=5x-16 is your answer and when you take the 3x from the left side then you also have to take it from the 8x on the other side
Yes, no x values repeated
