Question

Questions 1-4 I'm very confused on this

Answer 1

• All four are linear
• Slopes: 2, 1/2, - 2/3, 3/4

Explanation:

Top left

Rate of change is same for each step:

• 10 per each 5

Slope is:

• (25 - 15)/(5 - 0) = 10/5 = 2

Top right

Rate of change is same for each step:

• 1 per each 2

Slope is:

• (6 - 5)/(3 - 1) = 1/2

Bottom left

Rate of change is same for each step:

• -2 per each 3

Slope is:

• (30 - 32)/(5 - 2) = -2/3

Bottom right

Rate of change is same for each step:

• 3 per each 4

Slope is:

• (20 - 17)/(5 - 1) = 3/4
