KeemoD143 3 years ago Graph the equation. y = 4x – 3

1. Ahaanomegas

Mark the point (0, -3) and draw a line with slope 4. Boom!

3. KeemoD143

is it this ??

4. EulerGroupie

nope

5. cholo71796

Not quite, slope is rise over run. 4 is the same as 4 over 1, so it has to rise 4 and go over 1. Yours is going down 4 and over 1! Make it so it slopes the other way.

6. KeemoD143

this one

7. EulerGroupie

crossing point is off too

8. KeemoD143

okay this one

9. EulerGroupie

It crosses at y=3... then slope as @cholo71796 described

10. EulerGroupie

erp... oops... -3 crossing

11. KeemoD143

so no ??

12. cholo71796

Not quite, yours looks like it is crossing at (0, -2) instead of (0, -3). Good on the slope now though

13. KeemoD143

this one for sure ??

14. EulerGroupie

The thrid graph looks like it crosses at -3 on the y. The fourth one has a bad slope again.

15. cholo71796

Nah you had the slope good-- positive slopes go up and to the right-- but you got it crossing at (0, -3) now which is good

16. EulerGroupie

Going left to right it should be like you are going up hill if the slope is positive.

17. KeemoD143

okay help me with this then !!!!

18. KeemoD143

Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2?

19. EulerGroupie

You should post a new question, so your helper gets a new point.

20. EulerGroupie

Cholo did good for you... pick best response next to his name and start again.

21. KeemoD143

ok
