If the slope is 0, then x does not change at all.
take the given y coordinate, and make that the equation.
so y=-9, since the line will never change.
45 is the answer. It is the least common multiple of 5 and 9. Multiples of 5: 5, 10,15,20,25, 30, 35, 40, 45 and multiples of 9: 9, 18, 27, 36, 45
I think it’s 15..
cause you replace the x with -5 and solve the problem
