You can put this solution on YOUR website!
Get the equation into slope-intercept form: y = mx +b
The y-intercept is (0,b).
.
3x -2y = -6
.
-2y = -3x -6
.
y = 3/2x +3
.
(0,3) is the y-intercept
.
(x,0) is the x-intercept, so set y=0 and solve for x.
.
0 = 3/2x +3
3/2x = -3
x = -2
(-2,0)
.
With two points you can draw a line.
