Determine whether (-8,9) is a solution of 4x - 7y = 18
Step 1. (-8,9) means x=-8 and y=9. So substitute these values in above equation.
Step 2. Substituting the above values into above equation will yield
Step 3. Since the 29 does not equal to 18 then the point (-8,9) is not a solution to the equation.
I hope the above steps were helpful.
Good luck in your studies!
