Question

Express y in terms of x linear equation -2x+7-y=0 and check whether the point (-3,-2) lies as the line.

Answer 1

Step-by-step explanation:

y=- -2x+7

Now put the value of (-3, -2) in the equation.

LHS = -2(-3)+7-(-2)

= 6+7+2

= 15

≠ RHS

so the point (-3, -2) does not lie on the given line.

Answer 2

Answer:

Given equation: −2x+y−7=0

⟹−2x+y=7⇒y=2x+7

Now, check for x=−3 and y=−2 for the solution of given equation:

We have, RHS =2x+7

=2(−3)+7=−6+7=1



=−2= LHS

Hence, x=−3 and y=−2 isn't the solution of given equation.
