Sample Response: Distance is a function of time. The constant rate of change is 64. Write the equation Y=64x + 22. Substitute 4 in for x to get 278 miles,

Compare your response to the sample response above. Did your explanation

include that distance is a function of time?

include that the constant rate of change, or slope, is 64?

include the equation y = 64x + 22?

say to substitute 4 in for x to get 278 miles?

Yes the explanation satisfy the questions stated.

See below for explanation

Step-by-step explanation:

From the question, distance is said to be a function of time and the constant rate of change is 64.

y = 64x + 22

The above is in the form of a Linear equation:

y = mx + c

Where y = dependent variable (distance)

x = independent variable (time)

m = slope = distance/time

c = constant = 22

m = constant rate of change = 64

If x (time) = 4

y (distance) = 278 miles

y = 64(4) + 22

y = 256 + 22

y = 256 + 22

y = 278 miles

is only a line? i think so
