Divide x^2+77x+20 by x+9 what is the quotient and remainder ?

Count the rise and run to find the slope, 1. Next, find the y-intercept-(-1). Now make the slope-intercept equation-  y = 1x - 1. Double check, put x = 2 in the equation-  y = 1(2) - 1 (=) y = 2 - 1 (=) y = 1.

So, the slope-intercept equation for this line is y = 1x - 1.
