How do you find the slope and y-intercept of the line -7x - 9y = 27?

In this case our y-intercept, b, is -3 and our slope, m, is -7/9

Explanation:

One method we could use to find both is to rewrite the equation in slope intercept form, y=mx+b, where m is the slope, and b is the y-intercept.

−7x−9y=27
-9y=7x+27
y=-7/9x-3

In this case our y-intercept, b, is -3 and our slope, m, is -7/9! :D
