Question

find an equation of a line with the following points: (-7,-4);(-7,5)

Answer 1

x = -7

Answer 2

Use two point formula:

\[\large \frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}\]

Answer 3

If you try to use dat @waterineyes you are going to have a problem

Answer 4

Or there is no need as x coordinate of both the points are same..

That means line is parallel to y axis..

So:

x = -7 would be the equation..

Answer 5

Because that's a vertical line and its gradient is actualy undefined according to that formular

Answer 6

Actually Let me try..

Answer 7

It is not right but you will get the answer though:

\[\frac{y - y_1}{y_2 - y_1} = \frac{x - (-7)}{0} \implies x - (-7) = 0 \implies x = -7\]

Answer 8

i got the answer you did when i solved it

Answer 9

you're cheating Maths lol I like it....
