Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation: you would use the slop formula! First graph the points and draw the line (demos is a great virtual graphing website). Then use the Slop formula which is:

      y2 - y1

m=  ———-                  (1, -5)     (-3,  2)

      x2 - x1                  x1  y1      x2  y2

   

After filling in the formula and solving you’ll get 1.75 which is the same as 7/4
