Answer:

First and third relations represent functions.

Find the slope of the<br> equation below and show the work.<br> X=4
gladu [14]

Answer:

Undefined

Step-by-step explanation:

If a linear equation is organized in the form x=[a number], we know straight away that this line is a vertical line. This form is actually x=d, where d is the x-intercept of the line. Vertical lines do not have a y-intercept because they are parallel to the y-axis.

The slope of vertical lines is undefined.

I hope this helps!
