Question

write an equation is standard form of the line passing through the give pair of points. The line goes through the points (5,2) and (5,4). What is the equation of the line?

Answer 1

The general eq'n of a line is.
\[y = mx + b;\]

Answer 2

Now we find slope by taking the change in y/change in x
\[m= \frac{\Delta y}{\Delta x} = \frac{y2 - y1}{x2 - x1}\]

Answer 3

y2 = 4, y1 = 2
x2 = 5, y2 = 5

Answer 4

m=0

Answer 5

Whoa oh slope is undefined

Answer 6

yes that's I found out :D

Answer 7

m is not 0

Answer 8

hmm than that's where I am making mistake huh

Answer 9

if it was zero it would be flat. if its undefined it is vertical

Answer 10

but when you evaluate the equation for M what would you get?
y2-y1 / x2-y2 which comes to 2/0..?

Answer 11

divide by 0 = undefined, not 0 :)

Answer 12

Yep and you can't divide by zero because the word will explode

Answer 13

yes :D

Answer 14

so the answer would be x=5...

Answer 15

yes!

Answer 16

Just a vertical line.
