The grass on Julie's lawn was 4.5 centimeters tall right after she mowed it. Then the grass
grew at a rate of 2.1 centimeters per week.
Which equation models the relationship between h, the height of the grass in
centimeters, and w, the number of weeks since Julie mowed?
O w = 2.1h + 4.5
O w = 4.5h + 2.1
O h = 2.1w. + 4.5
O h = 4.5W + 2.1
