## spidergirl51 2 years ago find the slope and y intercept y=-10

1. CalebBeavers

y=-10 is the equation of a horizontal line. What is the slope of a horizontal line?

2. spidergirl51

0

3. spidergirl51

or is it undefined

4. CalebBeavers

No you're right its 0. Vertical lines have undefined slope. Now, if its a horizontal line with all y coordinates as -10, where do you think its gonna cross the y axis?

5. spidergirl51

in the middle

7. spidergirl51

so what would be the slope and y intercept is it 0 ?

8. CalebBeavers

|dw:1354072019147:dw|

9. spidergirl51

-2

10. CalebBeavers

The y intercept is -10

11. spidergirl51

but the slope is -2

12. CalebBeavers

No, we established the slope was 0

13. spidergirl51

oh yeah

14. spidergirl51

will it be the same x=6

15. spidergirl51

we have to do the same thing

16. CalebBeavers

X=6 is a vertical line

17. spidergirl51

slope is undefined

18. CalebBeavers

Right, and there will be no y intercept.

thanks
