Given the equation:


7x-2y=13

For each ordered pair, determine whether it is a solution to the given equation.

The first point: (3, 4)

So, we will substitute with x = 3 and y = 4


3\cdot7-2\cdot4=21-8=13

So, the answer will be Yes, it is a solution

The second point (-2, 5)


7\cdot(-2)-2\cdot5=-14-10=-24\\e13

so, the answer will be No it is not a solution

The third point: (1, -3)


7\cdot1-2\cdot(-3)=7+6=13

So, the answer will be Yes, it is a solution

The final point: (-5, 0)


7\cdot(-5)-2\cdot0=-35\\e13

so, the answer will be No it is not a solution

So, the answer will be Yes for the points (3, 4) and (1, -3)

And No for the points (-2, 5) and (-5,0)
