Find the slope:
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%28-10-%28-10%29%29%2F%285-%28-4%29%29
m=0%2F9
m=0
Now plug in the slope into the general point slope equation. General point slope equation:
y-y%5B1%5D=m%28x-x%5B1%5D%29
y-%28-10%29=0%2A%28x-5%29Plug in any point and the slope, lets use (5,-10) and m=-20/9
y%2B10=0Solve for y
y=-10
