Question

Circle the equation with a rate of change of 3.

y=3x+12
3y=2x+5
Y=6x-3

(Please explain how you got your answer)

Answer 1

`y = 3x + 12`

Explanation:

The rate of change is represented as the slope.

The problem is asking for a slope that is equal to 3.

y=6x-3 is incorrect, the equation is simplified and the slope is 6.

3y=2x+5 is incorrect, the slope is 2 and the equation isn't simplified.

y=3x+12 is correct, the equation is simplified and it's showing the correct slope.
