Try using the slope formula: $\Large m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} $

anonymous · Answer

i don't understand that

luigi0210 · Answer

$\large (x_{1}, y_{1}) $ and $\large (x_{2}, y_{2}) $ 

Match the coordinates with the formula $\large (2, 8) ~~ (6, 12) $

OMG i don't understand what x1 y1 x2 y2 means

mrnood · Answer

the two point s oyu have are (x1,y1) and (x2,y2)

in this case
x1=2
y1=8

x2=6
y2=12

put those numbers into the formula that @Luigi0210 gave you 

m is the answer for the slope...

wait so c?

mrnood · Answer

is that a guess?
care to show a little of your working?

anonymous · Answer

(x1-x2)
--------
(y1-y2)      so 4/4=1. C.

anonymous · Answer

@MrNood Yes?
