## Elementary and Intermediate Algebra: Concepts & Applications (6th Edition)

We know that $y=mx+b$, where m is the slope and b is the y-intercept. Using this, we find that the equation in slope intercept form is: $$-4y=12-9x\\ y=-\frac{12-9x}{4}$$ Thus, we see that the y-intercept is -3 and the slope is 2.25.
