To determine whether (9, -5) is a solution of 7x - y^2 = 4, we need to substitute the values x = 9 and y = -5 into the equation and check if it satisfies the equation.
So, let's substitute the values:
7(9) - (-5)^2 = 4
63 - 25 = 4
38 = 4
Since 38 is not equal to 4, (9, -5) is not a solution of the equation 7x - y^2 = 4.
Determine whether (9, -5) is a solution of 7x - y2 =4.
