Question 879294: Please tutors could you help me with this probelm ! 19. The number of weeds on a lawn can be written as the function W(d)=25d+60,where d represents the number of days since spring started.
a. Is the rate of change of this function constant? Explain your answer.

You can put this solution on YOUR website!
W(d)=25d+60 is a linear function with a slope of 25.

This slope is always 25 no matter where you are on the line since this function is a straight line.

This means that the rate of change is constant and it is 25. This "25" means that you will have 25 more weeds each day.
