mathmale · Answer

There are several equations one could use to describe a straight line.  Since you're given one point on your line and the slope of your line, we'll use the "point-slope" form:

$$y _{2}-y _{1}=m(x _{2}-x _{1})$$

Let's go over that a bit more:

You are given a point:  (3,-4).     This says that when x=3, y=-4.

Please copy the "point-slope" equation above and replace $$y _{1}$$   with -4 and replace $$x _{1}$$ with 3.

2−-4=m(x2−3)

mathmale · Answer

$$y _{2}-y _{1}=m(x _{2}-x _{1})$$      You are on the right track.   It's just that those pesky subscripts 1 and 2 are a bit hard to type in.
