8. NickR

lmao ya do it while you can

What is an equation for the line that passes through points (–1, –4) and (1, 4)? Write the equation in slope-intercept form. (2 points)

10. NickR

um 1 sec

11. NickR

\[m=(y _{2}-y _{1})/(x _{2}-x _{1})\]

12. NickR

this is going to be your slope plug in your #'s (x1,y1)(x2,y2)

13. NickR

@lucwex you get what to do?

14. lucwex

ya i think im going to carry on tomorrow im pooped

15. NickR

ok this is what i got m=(4-(-4))/(1-(-1))

16. lucwex
