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

96 → B
substitute w = 12 into the equation D = 3w + 60
D = (3 × 12 ) + 60 = 36 + 60 = 96
I’m not sure what the question is but I’m just gonna assume that you need the equation: y=1/2x+5
