Answer:
y = 2x + 11
Step-by-step explanation:
The point slope formula for a line is
y - y1 = m(x - x1)
We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):
y - 3 = 2(x + 4)
y - 3 = 2x + 8
See Below
6x - 12 + x = 9
6x + x - 12 = 9
Collect like terms
7x - 12 = 9
Add both sides 12
7x - 12 + 12 = 9 + 12
7x = 21
Divide both sides by 7
7x ÷ 7 = 21 ÷ 7
x = 3
