The solutions for the equation are
(-2, 7)
(-5, -25)
How to find whether the options is a solution
In each option, we substitute the value of x and solve for y. Then we compare the value of y to the value given
For x = 7
y = 6(7) + 5
y = 47
No, this is not a solution
For x = 9
y = 6(9) + 5
y = 59
No, this is not a solution
For x = -2
y = 6(-2) + 5
y = 7
Yes, this is a solution
For x = -5
y = 6(-5) + 5
y = -25
Yes, this is a solution
