Thoughts?

anonymous · Answer

none. I don't know how to solve it

anonymous · Answer

May I answer ?:)

anonymous · Answer

sure you can! @E.ali

anonymous · Answer

I'm going to straight up give you the answer; since the graph to the function of the equation is linear, you can utilize
$$y-y_{0}=k(x-x_{0})$$
$$k=\frac{\Delta y}{\Delta x}$$

anonymous · Answer

Just utilize the values you're given through the graph and insert them into the equation. You'll get the equation for the function.

anonymous · Answer

K !
m=y2-y1/x2-x1
in there :
x1=-2
y1=4
x2=1
y2=13
So use it again :
y-y2=m(x2-x)
Got it ?:)

anonymous · Answer

You should use k (instead of m) in this to be stringent E.ali! :D

okay thanks you guys! :)
