Answer- To determine if Y=-8 is a function, you must do the vertical line test. If you were to plot Y=-8 on a coordinate plane, you would see that at the point of (0,-8)[which is what Y=-8 is also] is on the Y axis and makes a horizontal linet hat passes through (o,-8).
-5s-5x+5s+50 Combine like terms
5x+50
-5= -5x-10
Plus 10 from both sides
5=-5x
X = -1
