Show that points a(1 ,2) b(-1 -16) and c(0 -7) lie on the graph of the linear equation y=9x-7

All three points belong to the line

Step-by-step explanation:

The given equation of a line is:

y = 9x - 7

We have to test if the following points lie on the graph of the line.

Point a(1,2)

Use the values x=1, y=2 and test for equality:

2 = 9(1) - 7 = 9 - 7 = 2

2 = 2

Since equality is true, point a belongs to the line.

Point b(-1,-16)

Use the values x=-1, y=-16 and test for equality:

-16 = 9(-1) - 7 = -9 - 7 = -16

-16 = -16

Since equality is true, point b belongs to the line.

Point c(0,7)

Use the values x=0, y=-7 and test for equality:

-7 = 9(0) - 7 = 0 - 7 = -7

-7 = -7

Since equality is true, point c belongs to the line.

All three points belong to the line

Option 1 because it will be easier to keep up with since you'e getting the same amount every day.
