Final answer:
The rate of change in the given equation is 17.5, which means that for every increase of 1 in the x-value, the y-value will increase by 17.5.
Step-by-step explanation:
The rate of change in this equation can be determined by looking at the coefficient of the independent variable, which is the variable that represents the x-values. In this case, the equation is y=17.5x+19. Therefore, the rate of change is 17.5. This means that for every increase of 1 in the x-value, the y-value will increase by 17.5.
