Answer:
y = [tex]-\frac{2}{3}x + 1[/tex]
Step-by-step explanation:
When y = mx + b
I. Find m.value
If m = (y2 - y1) / (x2 - x1)
= ( -1 - 3) / (3 + 3)
= -4/6
m = -2/3
II. Find b.value
If y = mx + b, when y is 3, x is -3 and m is -2/3
3 = -2/3(-3) + b
3 = -2(-1) + b
3 = 2 + b
3-2 = b
b = 1
That makes y = -2/3(x) + 1
