Answer:

y= -3x+0

Step-by-step explanation:

  • (-1,3) is, -1=x1 3=y1, (3,-3) is 3=x2 -3=y2
  • formula is y2-y1/x2-x1=
  • -3-3/3-1= -6/2= -3/1= -3
  • -3= slope or (m), use either (-1,3) or (3,-3), i used (-1,3) because its easier
  • formula is y-y1=m(x-x1) (-1,3) is -1=x1 3=y1
  • y-3= -3 (x-(-1)) ------> -1 becomes positive because there are two negatives  
  • y-3= -3(x+1) ------> then distribute
  • y-3= -3x-3 -------->get the y alone

          +3        +3

  • y= -3x+0
