3.
Write the equation of the line that is parallel to the line 4x - 3y = -12 and passes through the point (-3, 4). (2 points)

a) y = 4/3 x + 8

b) y = 4/3 x + 3

c) y = -3/4 x + 8

d) y = -3/4 x + 3

Respuesta :

Rearrange into y= ...
3y = 4x +12
y = 4/3x + 4
Gradient of line = gradient of parallel line = 4/3
y-y1=m(x-x1)
y-4=4/3(x+3)
y-4 = 4/3x + 4
y = 4/3x + 8
Option A
