kkutie7 · Answer

so you want to use this equation
$$y=m(x-x)+y$$

kkutie7 · Answer

or better
$$y=m(x-x_{1})+y_{1}$$

kkutie7 · Answer

you have m and 
$$x_{1}=5$$
$$y-{1}=-2$$

kkutie7 · Answer

*$$y_{1}=-2$$

anonymous · Answer

y=mx+b

kkutie7 · Answer

$$y=\frac{-2}{5}(x-5)-2$$
can you do it from here?

anonymous · Answer

so y=-2/5x but idk the rest. im kinda confused @Kkutie7

kkutie7 · Answer

Ok so use the equation I gave you and multiply through here look 
$$y=\frac{-2}{5}x+\frac{10}{5}-2$$
$$y=\frac{-2}{5}x+2-2$$
so its just basically the slope.

anonymous · Answer

so y= -2/5x+2-2 is the answer?

kkutie7 · Answer

yes and no =) you can 2-2=0 so its just y=-2/5x
