First, you need to find the slope using the equation m=(y

_{2}-y_{1})/(x_{2}-x_{1}).Next, use the point-slope formula, with the value for m that you just found and one of the given points, to find an equation of this line: (y-y

_{1})=m(x-x_{1})Then, put the equation into the standard form of Ax+By=C, where A, B, and C are all integers.

That should get you started... :) Let me know if you get stuck.

So, m=(-4-(-1))/4-(-3))=(-4+1)/(4+3)=-3/7

Next, use the point-slope formula, with the value for m that you just found, to find an equation of this line: (y-y1)=m(x-x1)

So, (y-(-1))=-3/7(x-(-3))

(y+1)=-3/7(x+3)

Then, put the equation into the standard form of Ax+By=C, where A, B, and C are all integers.

So, if you multiply through by 7, you get:

7(y+1)=-3(x+3)

Distribute:

7y+7=-3x-9

Add 3x and subtract 7 on both sides to get:

3x+7y=-16
