The slope is -9/7. I don’t have an explanation because I used an online calculator but that’s the answer in case you don’t have to show work.

(x+2)(x-18)=0 FIND THE SOLUTIONS OF THE EQUATION

vladimir2022 [97]

Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2

x - 18 = 0
x = 18

I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
