Answer:
rate of change = 3
Step-by-step explanation:
rate of change can be found in different ways.
1. first by comparing the equation with y=mx+c, if it is a linear equation which is right in this case.
y=mx+c
y=3x-10
m=3, c=-10
where m=slope or in other terms rate of change as
m=change in y upon change in x
2. in other case you can take a derivative.
y=3x-10
dy/dx=3.
