3%28x-2y%29=-12
Dividing both sides of the equal sign by 3 we get
x-2y=-4
When y=0 x=-4
The x-intercept is the point (-4,0), or simply x=-4 , since we know an x-intercept point always has y=0 .
When x=0 -2y=-4 --> y=2
The y-intercept is the point (0,2), or simply y=2 , since we know a y-intercept point always has x=0 .

y=-2x-8
When x=0 y=-8
The y-intercept is the point (0,-8), or simply y=-8 , since we know a y-intercept point always has x=0 .
When y=0 ,
0=-2x-8 --> 2x=-8 --> x=-4
The x-intercept is the point (-4,0), or simply x=-4 , since we know an x-intercept point always has y=0 .
