Step-by-step explanation:
No pongas foto por que no puedo ver y no te puedo responder
Given two points (X1,Y1) and (X2,Y2) on a line, the slope =(Y2 - Y1) /(X2 - X1).
You are given the points (1,3) and (3,-2). Implying X1 =1 , Y1 =3, X2=3, Y2=-2
Use the formula for the slope above to answer the question. If you still have problems getting the correct answer, ask for more help.
Your answer should be a negative fraction or decimal if you are using a calculator.
