## anonymous one year ago What is the slope of the line x = −5? (1 point) Undefined 0 −5 5 Anyone know please?

1. Nnesha

vertical line = 0 slope (remember slope = rise /over) horizontal line = undefined

2. anonymous

So it's 0?

3. Nnesha

yes right bec = -5 would be the vertical line

4. anonymous

Ok ty

5. anonymous

It said it was wrong :(

6. Nnesha

oh god facepalm i switched x and y i'm soo sorry

7. Nnesha

x=vertical line = undefined slope y=horizontal line = 0 slope bec x values would be the same and if you use the formula $\huge\rm \frac{ y_2-y_1 }{ x_2 -x_1 }$ we would get 0 at the denominator (bec the line have same x-coordinate ) and when you subtract same two numbers you will get and if we get 0 at the denominator then answer would be undefined

8. Nnesha

|dw:1442433610575:dw| same x value for ally-coordinates

9. Nnesha

so $\huge\rm \frac{ y_2 - y_1 }{ x_2-x_1 }= \frac{ y_2 -y_1}{ -5-(-5)}$

10. Nnesha

did you get it ? and i'm sorry ...:(

its ok :( and i got a C- atleast not a D :/
