In order to receive bonus pay for summer work, Kelly has to work at least 60 hours in her online course. Due to other commitments, she is unable to work more than 120 hours. Use set
notation and interval notation to represent the number of hours she can work in the online
course.

The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Step-by-step explanation:

Given the points

Finding the slope between  (-7, 1.3) and (-7, 14.2):

It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.

In other words, the given line is vertical.

i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0

We know that the slope of a vertical line is undefined.

i.e.

Using the slope formula

Slope =  [14.2 - 1.3] / [0]

Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
