Write an equation in slope-intercept form for the line that passes through (4, -4) and is parallel to 3 + 4x = 2y – 9.

3 + 4x = 2y - 9
2y = 4x + 3 + 9
2y = 4x + 12
y = 2x + 6

if it's parallel, than if y = ax + b, a = 2 and you need to find b

(4, -4)
x = 4
y = -4

-4 = 2*4 + b
-4 = 8 + b
b = -12

so an equation is:
y = 2x - 12
