## anonymous one year ago A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x + 6 y = 2x + 7 y = 2x + 4 y = 1 over 2 x + 10

1. pooja195

$\huge~\frac{ y_2-y_1 }{ x_2-x_1 }$

subtract 4-2 then subtract 12-8

3. pooja195

(x1,y1)(x2,y2)

4. pooja195

Thats the slope formula we need to use to figure out what the slope is :)

5. anonymous

its C

6. anonymous

but i dont understand how to plug it in i akready know the formula

7. pooja195

Ok (x1,y1) right?

8. anonymous

ok

9. pooja195

plug that much in

10. anonymous

oh wait so c was right ?

11. anonymous

sorry im new to slopes haha

12. anonymous

yes i learned a short cut

@aloud explain your answer. By now you should know that direct answers arent allowed.

alright so u have 2,8 and 4,12 so u move 2 under 4 and subtract the and u get 2 the u put 8 under 12 and u get 4 y=2x=4

15. anonymous

i mean y=2x+4 lol
