Question

Show that the points A(1, 2) and B (0, -7) lie on the graph of the linear equation

y = 9x – 7.​

Answer 1

Answer:

if we want these coordinates to lie on graph of y = 9x - 7

We have to verify

i) A(1,2) x = 1 and y = 2

2 = 9×1 - 7

2 = 9-7

2=2

ii) B(0,-7) x = 0 and y = -7

-7 = 9×0 - 7

-7 = 0-7

-7 = -7

Hence Proved

Answer 2

Answer:

if we want these coordinates to lie on graph of y = 9x - 7

We have to verify

i) A(1,2) x = 1 and y = 2

2 = 9×1 - 7

2 = 9-7

2=2

ii) B(0,-7) x = 0 and y = -7

-7 = 9×0 - 7

-7 = 0-7

-7 = -7

Hence Proved
