For this case we must indicate which of the given points do not belong to the graph of the following equation:

y = 5x-5

We substitute each of the points in the equation:

$A. (x, y) = (0,5)\\5 = 5 (0) -5\\5 = 0-5\\5 = -5$

It is not fulfilled, then the point (0,5) does not belong.

$B. (x, y) = (1,0)\\0 = 5 (1) -5\\0 = 5-5\\0 = 0$

It is fulfilled, then the point (1,0) belongs.

$C. (x, y) = (- 5,0)\\0 = 5 (-5) -5\\0 = -25-5\\0 = -30$

It is not fulfilled, then the point (-5,0) does not belong.

Answer:

the points (0,5) and (-5,0) do not belong to the graph
