which function has greater unit rate?

Question

x 3 4 5 6
y 21 23 25 27

y=-3+12
A. the equation
B. the table

Answer 1

To determine the unit rate for each function, we need to compare the rate of change in y for each increase in x.

For the equation y = -3x + 12:
- When x increases by 1 (from 3 to 4), y increases by (-3(1)) = -3
- The unit rate for this function would be -3.

For the table:
- When x increases by 1 (from 3 to 4), y increases by 23-21 = 2
- The unit rate for this function would be 2.

Therefore, the table has a greater unit rate than the equation.
