The intercept method is easy if the x and y terms
are on the left side of the equation.
3y -2x = -12
This method calculates two points (x,0) and (0,y).
Find the x in (x,0), set y=0
3(0) -2x = -12
Then divide both sides by -2
0 -2x/-2 = -12/-2
So x = 6
The x-intercept is (6,0)
Find the y in (0,y), set x=0
3y -2(0) = -12
Then divide both sides by 3
3y/3 + 0 = -12/3
So y = -4
The y-intercept is (0,-4)
as we graph the intercepts.
