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

   w = 2.1h + 4.5

Step-by-step explanation:

w is the number of weeks since Julie mowed the lawn

h is the height of the grass

w=the rate the grass grew at and the grass on Julies lawn

w=2.1h+4.5

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
