did you check some points given?

anonymous · Answer

?

anonymous · Answer

y=x+2

anonymous · Answer

i think it is B

anonymous · Answer

remember y=mx+b

anonymous · Answer

so its D? i suck at math... :P

misty1212 · Answer

lol me too 
it crosses the y axis at 2, so you expect to see a $+2$ out at the end

anonymous · Answer

lol

triciaal · Answer

you have when x = 0 y = 2 and when y = 0 x = -2 
this gives (0,2) and (-2, 0)

anonymous · Answer

ok

anonymous · Answer

yep :) that ecuation is quite useful

misty1212 · Answer

so yeah, go with D since that is the only one with a $+2$

anonymous · Answer

$$m=\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }$$
use the formula for the slope by plugging in the x and y coordinates for two separate points on the graph

anonymous · Answer

c has a plus +2

misty1212 · Answer

as for the slope, with your eyes you see the line goes right one, up one, making the slope 1

misty1212 · Answer

oh yeah, so it does, doesn't it
but the line goes over one, up one, not over one, up two

anonymous · Answer

ok so i will go with D

correct
