The y-intercept is -5.
2x - 3y = 15
-3y = -2x + 15
y = 2/3x - 5
the y-intercept is the number in slope intercept form that does not have a variable, the minus sign makes the intercept negative.

8x = 2x + 15 6x = 15 x = 15/6 = 2.5
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
x2-2x-15 = (x+3)(x-5) when factored
-3(x-5)=2x -3x+15=2x 15=5x x=3
