Find the slope
$$\LARGE \frac{y_2-y_1}{x_2-x_1}=slope$$

babynini · Answer

Does that make sense? :) take your two points
You have:
(2, 5) which is (x1,y1)
(4,3) which is (x2, y2)

pooja195 · Answer

The slope is not 2....try again.

c?

babynini · Answer

remember that your equation looks like this:
y=(slope)x+b
So if you take your points and do what pooja said than you will find at least your slope! :)

jacob902 · Answer

y = -x + 7?
