Question

Write an equation of a line that has an undefined slope and goes through the point (9,-5)

Answer 1

Answer:

• x= 9

Step-by-step explanation:

Slope formula is

• m = Δy/Δx

When Δx = 0 the denominator of the fraction is zero, hence it is undefined

So this is a vertical line

A vertical line passing through the point (9, -5) is x= 9

So the answer is x= 9

Answer 2

Answer:

x=9

Step-by-step explanation:

a undefined line is a straight line so the y value does not matter sence it goes through all the y values
