Question

Show that the points A (1, 2), B ( – 1, – 16) and C (0, – 7) lie on the graph of the linear equation y = 9x – 7.​

Answer 1

Step-by-step explanation:

FOR A(1,2)

y=9x-7

LHS

y=2

RHS

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

LHS = RHS

FOR B(-1,-16)

LHS

y=-16

RHS

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

LHS=RHS

FOR C(0,-7)

LHS

y=-7

RHS

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

LHS= RHS

while substituting corresponding values of x and y in given equation if we get LHS=RHS then given value is solution of given equation or lie on graph of given equation.
