Question

graph the line containing the point p and having slope m. p=(1, - 7); slope undefined. use the graphing tool to graph the line. click to enlarge graph

Explanation:

Step1: Recall slope - line relationship

An undefined slope means the line is vertical.

Step2: Identify x - coordinate of the point

The point is $P=(1, - 7)$. The x - coordinate is $x = 1$.

Step3: Graph the line

A vertical line passing through $x = 1$ will have all points with $x=1$ and different y - values.

Answer:

Graph a vertical line passing through the point $(1,-7)$ on the coordinate - plane. This line will have the equation $x = 1$ and will cross the x - axis at the point $(1,0)$ and pass through all points of the form $(1,y)$ where $y\in R$.
