Slope intercept form is y=mx+b, where m is just some constant number and so is b. First we need to isolate the y. So if we are given 3y-4x=9, we should add 4x to both sides. Now we have 3y=4x+9, so we can divide both sides by 3, which gives us y=(4/3)x + 3. The slope is 4/3 and the y-intercept is 3.
