## Steph_Rawr352 Group Title PLEASE HELP!! Find the equation in standard form which passes through (–1, 4) and (0, 9) one year ago one year ago

1. surdawi Group Title

$m=\frac{ y2-y1 }{ x2-x1 }$ $y - y1 = m*(x - x1)$

2. Steph_Rawr352 Group Title

The slope is 5 right?

3. Steph_Rawr352 Group Title

y-9 =5(x-0)

4. surdawi Group Title

yes, but still not done yet solve for y y = mx + b

5. Steph_Rawr352 Group Title

I don't really know how to use that equation/: i never learned it

6. surdawi Group Title

y-9 =5(x-0) distribute the 5 what do you get?

7. Steph_Rawr352 Group Title

y-9 = 5x - 0 ?

8. surdawi Group Title

yes now move the 9 to the other side what do you get?

9. Steph_Rawr352 Group Title

then subtract 5x from both sides?

10. surdawi Group Title

no you need to add 9 to both sides

11. surdawi Group Title

y-9 = 5x +9 +9 y = 5x + 9

12. Steph_Rawr352 Group Title

wait but I need to put it in standard form

13. surdawi Group Title

y = 5x + 9 ok subtract the 5x and you will be good

14. surdawi Group Title

Standard Form: Ax + By = C slope-intercept form: y = m x + b

15. Steph_Rawr352 Group Title

yeah i know but I think I got it now I figured it out thank you for helping me understand tho c:
