Which of the following points does not lie on the graph of y = 5x - 5? (0, -5) (1, 0) (-5, 0)

Nnesha (nnesha):

replace x and y by their values (x ,y ) and solve if both sides are not equal then that order pair does not lie on the graph :)

..?

Nnesha (nnesha):

for example |dw:1424908604965:dw|fist order pair where x is 0 and y is -5 so substitute x and y values into the equation

OpenStudy (anonymous):

I don't understand

Nnesha (nnesha):

order pair where first value is x and 2nd one is y \[\huge\rm (x ,y)\] so i'm saying that use one of order pair and replace x and y by their values into the equation

Nnesha (nnesha):

for example first answer choice ( 0 , -5) where x = 0 and y = -5 so replace x by 0 and y by -5 into the equation \[y = 5x -5\]

Nnesha (nnesha):

\[-5 = 5(0) -5\] now solve this if both side r NOT "equal"then this yis your answer
