Find the slope by using this equation
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=%280%29%2F%289%29
m=0
Plug in value of m into
y=mx%2Bb
y=0x%2Bb
Plug in any point, I'm selecting (-4,-10), into the equation
-10=0%2A%28-4%29%2Bb Since m=0, it becomes
-10=b
So the equation is
y=-10
