y=-1/4x+2 and y+3=7(x+1)

Explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept. Since m=-1/4 and b=2, plug those in to get y=-1/4x+2.

The general equation for point-slope form is (y-k)=m(x-h), where m is slope and (h,k) is some point on the line.
We'll use (-1,-3) as (h,k) for this line. For the (y-k) part, we have y-(-3), or y+3.
Likewise, (x-h)=(x-(-1)), or x+1.

Plugging in this information gives us y+3=7(x+1).

You know, the really beautiful thing about algebra is that it allows us to measure the unknown! Have fun!
