Which graphs do not show a constant rate of change? Check all that apply.
On a coordinate plane, a parabola opens down.
On a coordinate plane, a line has a negative slope.
On a coordinate plane, a horizontal line is graphed.
On a coordinate plane, a curve curves downwards.
It does not change it will always stay at the same y but just different x. The rate of change/slope is the change in y divided by a corresponding change in x.
