Question

Linear Function Table

Answer 1

a. The difference between two outputs that are 1 unit apart.

You need to Use y2 - y1 / x2 - x1 to find the difference

I will choose x2 as 1 and x1 as 0

(29 - 21) / (1 - 0)

8/1 so The difference is 8 per 1 unit.

b. Use the same formula

I will choose -3 as x2 and -5 as x1

(5 - (-11)) / (-3 - (-5))

(5 + 11) / (-3 + 5)

16 / 2 so the difference is 16 per 2 units.

c. I will choose 2 as x2 and -1 as x1

(45 - 21) / (2 - (-1))

24/3 so the difference is 24 per 3 units.

d. The ratios of the differences to the input intervals reduced all equal each-other, which is 8 per 1 unit.
