Write the equation of the line that has an undefined slope and passes through the point (4,7).

There is no y as part of the equation. It is a vertical line through 4 on the x axis. Every point on this line has an x coordinate of 4. Recall that all vertical lines have undefined slopes. I picked 4 because it is the x coordinate of the given point (4,7).

x=4

Step-by-step explanation:

A vertical line has an undefined slope

Vertical lines are of the form

x=

This passes through the point

(4,7)  so it must go through x=4

x=4

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
