Question

A line with an undefined slope passes through the points (9,6) and (n,9). What is the value of n?

Answer 1

n = 9

Explanation:

A line with an undefined slope is a vertical line, with equation

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

the line passes through (9, 6 ) and (n, 9 ), with x- coordinate of 9, then

then equation is x = 9

so value of n = 9 , that is the point (9, 9 )
