Question

graphs of proportional relationships ada math assessment part a. interpret each plotted point in the graph. (0, 0): you earn $0 for working 0 hour(s). (1, 15): you earn $15 for working 1 hour(s). (4, 60): you earn $60 for working 4 hour(s). part b. identify the unit rate and find the slope of the line. the unit rate is $□:□ hour(s). the slope of the line is □.

Explanation:

Step1: Find unit rate

Unit rate = $\frac{\text{Total earnings}}{\text{Total hours}} = \frac{\$15}{1\text{ hour}}$

Step2: Calculate slope

Slope = $\frac{\text{Change in earnings}}{\text{Change in hours}} = \frac{60-0}{4-0} = 15$

Answer:

Part B:
The unit rate is $\$15$ : $1$ hour(s).
The slope of the line is $15$.
