Question

show that point a=(1, 2)and b=(0, 7) lie on linear equation y=9x-7​

Answer 1

Answer:

a point lie on a line on graph then the coordinates satisfies the equation of the line

A(1,2)

y=9(1)-7 = 2 satisfied

B(-1,-16)

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

simulation C will also satisfy the equation

Answer 2

Answer:

Step-by-step explanation:

First, assume that A(1, 2) lie on a line with equation y = 9x - 7 , then

2 = 9×1 - 7

2 = 2

Yes, point A(1, 2) lie on a line with equation y = 9x - 7

Next, assume that point B(0, 7) lie on a line with equation y = 9x - 7 , then

7 = 9×0 - 7

7 = - 7 false statement ⇒ that point B(0, 7) DOES NOT LIE on a line with equation y = 9x - 7
