Question 1094718
3x+4y–12=0

Solve for y

y = - 3x/4 + 3

The slope is the coefficient of x, that is slope = -3/4. The y intercept is the value of y when x - 0. Plugging back x = 0 in the equation above, you see that y = 3.

It's always a good idea to check directly in the original equation. 3*0 + 4*3 - 12 = 0 as expected
