Answer:
H: 0, 1, 2, 3, 4, 5
plumber 1: 20, 70, 110, 160, 210, 260
plumber 2: 0, 60, 120, 180, 240, 300
plumber 1: C = 50h + 20
plumber 2: C = 60h
To find the slope(m), use the slope formula:
And plug in the two points on the line
(-3, 7) = (x₁, y₁)
(5, -1) = (x₂, y₂)

(two negative signs cancel each other out and become positive)

Simplify the fraction
m = -1

The answer is A (3). In the question you are given a list of numbers, these are the results from the science project. In the list, the number 12 appears 5 times, therefore 5 dots are added above the number 12 on the dot plot. 11 appears once, 13 appears 3 times, 14 appears 3 times and 15 appears three times. Hope this helps.
