solve for y, and state the slope and y-intercept? The equation is:
3x - 4y = -12
:
Subtract 3x from both sides
-4y = -3x - 12
:
y has to be positive, mult by -1, change all the signs
4y = 3x + 12
:
Divide both sides by 4
y = 3%2F4x + 12%2F4
y = 3%2F4x + 3
This is the "slope/intercept" form therefore:
slope = 3%2F4, y intercept = 3
