Question

show that the point (1,2)lie on the graph linear equation y=9x-7​

Answer 1

Step-by-step explanation:

If the point (1,2) lie on the graph of linear equation y = 9x - 7 it should satisfy the given equation.

Substitute x = 1 and y = 2

LHS = y = 2

RHS = 9x - 7

= 9(1) - 7

= 2

LHS = RHS

Therefore, this point lies on the graph of linear equation.
