Answer 1

The two variables are the x and y in hours and dollars respectively

the correct equation is y = 1.25x

Melissa charges $1.25 an hour per to pet sit

Step-by-step explanation:

Using the given table and the graph:

The two variables are the x and y in hours and dollars respectively

To get the correct equation, we need to find the slope of the graph

slope = change in y/change in x

`m\text{ = }(y_2-y_1)/(x_2-x_1)`

Using any two points: (1, 1.25) and (2, 2.5)

slope = (2.5 - 1.25)/ (2-1) = 1.25/1

slope = 1.25

Since the graph starts from the origin, ther will be no intercept.

Equation of line: y = mx + c

y = 1.25x + 0

Hence, the correct equation is y = 1.25x

When x = 1 hour

The cost per pet sitting is $1.25

Hence, Melissa charges $1.25 an hour per to pet sit
