The average rate of change between from 9:00 to 9:27 is 2.15°F increase per minute
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the temperature at x time.
By 9:00 a.m. the same day, the temperature was 54°F. By 9:27 a.m., the temperature was -4°F
m = (-4 - 54)/27 minutes = -2.15
The average rate of change between from 9:00 to 9:27 is 2.15°F decrease per minute

Answer:
Step-by-step explanation:
m=marta's rope
d=dilbert's rope
3d-10=m
m+d=120
Then you can substitute equation 1 into the second one
(3d-10)+d=120
3d-10+d=120
4d-10=120
4d=130
d=32.5
m+d=120
m+32.5=120
m=120-32.5
