X = 4.33333333333
y = 5.33333333333
z = 6.33333333333
Opposite sides of angles are equal so
x+12=4x-48
12+48=4x-x
60=3x
x=60/3
x=20
Answer:
y = -2/3x + 2

Well since we already got the y-intercept to find slope we'll use the points,
(3,0) and (0,2).
Formula: 
Plug in the given points,

Slope = -2/3
Slope-intercept: y = -2/3x + 2
