## flyinglikeabird? 3 years ago Write the equation of the line in Slope-Intercept form, Then graph the equation by using either the slope-intercept equation or by using x- and y-intercepts. The line contains points (3, 5) and (3, 8).

1. flyinglikeabird?

I have already did this problem, just need to make sure I have done it right. 0 is the slope obviously because the line is always on the x-axis.

2. CalebBeavers

Slope is undefined, which means its a vertical line. So the equation is gonna be x=whatever the x coordinate always is. In this case x=3

3. flyinglikeabird?

Ahh, okay. Thanks, that's all I needed.

4. CalebBeavers

You're welcome

5. flyinglikeabird?

I have one more problem like this. Can you help me through it?

6. CalebBeavers

Yep.

7. flyinglikeabird?

Alright, thanks. Here it is. The line contains points (2, -1) and (0, 4).

8. CalebBeavers

And you want slope intercept form?

9. flyinglikeabird?

Yes, same as the others.

10. CalebBeavers

Alright, well if you notice, one of your points is the y intercept. So if we find the slope we can just plug those in and were done.

11. flyinglikeabird?

Slope is -2

12. CalebBeavers

You should have got -5/2

13. flyinglikeabird?

Hmmm, trying again one min.

14. flyinglikeabird?

Ahh, okay. Gothcha.

15. CalebBeavers

Alright, slope intercept form is y=mx+b where m=slope and b=y coordinate of the y intercept. So plug those in and what do you get?

16. flyinglikeabird?

2 = -5/2-1 + 2 or something like that....

17. CalebBeavers

No, all you have to plug in is m and b. y=-5/2x+4

18. flyinglikeabird?

Oh...yeah. heh I'm always gettin the steps mixed up.

19. CalebBeavers

Yep. So now you're done and thats your answer. Understand how to do it now?

20. flyinglikeabird?

Well yes and no. I'll most likely forget anyway.
