Question

What is the equation of the line that passes through the point (4, 6) and has an

undefined slope?

Answer 1

x = 4

Explanation:

a line with an undefined slope is a vertical line parallel to the y- axis, with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (4, 6 ) with x- coordinate 4 , then

x = 4 ← equation of line
