Question

I don't understand this at alllll considering my answer options. Help?

Write the equation of a line with an undefined slope and point (1, 7).

My answer options:

A. y=7
B. x=7
C. y=1
D. x=1

This seriously makes no sense to me.

Answer 1

I'm not looking for an answer. I just need to know how to solve it.

Answer 2

Lines with undefined slopes are

a) horizontal

or

b) vertical

???

Answer 3

ahhhh, gotcha! duhh so simple! lol thanks!

Answer 4

that explains the x and y. x is horizontal. y is vertical.

Answer 5

ok... so slopes go between m = 0 ( a horizontal line)



an undifined slope has a value of zero in the denominator...

Answer 6

kinda...

Equations such as x = 2, x = 3, x =4, etc are all vertical lines (with undefined slopes)

Equations such as y = 1, y = 5, y = 17, etc are all horizontal lines (with slopes of zero)

Answer 7

So because it has an undefined slope, its in the form

x = k

where k is any number

Answer 8

ohh.. wait a minute. i was thinking of something else. lol what you just said made it clearer. thanks! :)

Answer 9

so what value of k will make x = k go through (1, 7) ?
