Choose the equation that has solutions (5,7) and (8,13).
Alekssandra [29.7K]
<h2>Answer:y=2x-3</h2>

Step-by-step explanation:

(x_{1},y_{1}) is called solution of a equation if (x_{1},y_{1}) satisfies the equation.

Consider the equation y=2x-3,

For point (5,7),

LHS=y=7

RHS=2x-3=2(5)-3=10-3=7

So,RHS=LHS

The point (5,7) satisfies the equation.

For point (8,13),

LHS=y=13

RHS=2x-3=2(8)-3=16-3=13

So,RHS=LHS

The point (8,13) satisfies the equation.

So,both the points satisfy the equation y=2x-3
