Question

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

Answer 1

\[\huge~\frac{ y_2-y_1 }{ x_2-x_1 }\]

Answer 2

subtract 4-2 then subtract 12-8

Answer 3

(x1,y1)(x2,y2)

Answer 4

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

Answer 5

its C

Answer 6

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

Answer 7

Ok (x1,y1) right?

Answer 8

ok

Answer 9

plug that much in

Answer 10

oh wait so c was right ?

Answer 11

sorry im new to slopes haha

Answer 12

yes i learned a short cut

Answer 13

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

Answer 14

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

Answer 15

i mean y=2x+4 lol
