Can u help me please

Slope = 3

Y intercept = 18

Work Shown:

m = slope

m = (y2-y1)/(x2-x1)

m = (0-(-9))/(-6-(-9))

m = (0+9)/(-6+9)

m = 9/3

m = 3 ... is the slope

y = mx+b

y = 3x+b plug in the slope

-9 = 3(-9)+b ... plug in the point (x,y) = (-9,-9)

-9 = -27+b

-9+27 = -27+b+27 adding 27 to both sides

18 = b

b = 18 ... is the y intercept

We found that m = 3 is the slope and b = 18 is the y intercept

y = mx+b turns into y = 3x+18

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
