What would be the rate of change in y=1/2+3?!

the rate of change is 1/2

Step-by-step explanation:

The rate of change is described by the change in y over the change in x. I'm guessing you meant to put an x after 1/2. The equation you wrote is in y-intercept form, as it gives us the slope and y-intercept. Slope is the same as rate of change. In simple terms, the number beside x is the rate of change. 1/2
