Answer: The answer for this would y=-2x+b in slope form and y=-2x+3 in standard form.
Explanation:
First we have to figure out what the slope is and you should this formula y2-y1/x2-x1 you plug in the coordinates and your equations should look like this -3-5/3-(-1)= -8/4 which simplified into -2. In standard form you put in the same equation but plug in the coordinates with the slope so it would look like this. -3=-2(3)+b and you would get 3 as b and then you substitute it in the equation again y=mx+b and it should like this in standard form y=-2x+3.
