I thought I chose the right answer but I didn’t so can someone help me please

Answer:
The slope of the table is positive so 6(3) miles were ran every 4(2) hours the unit rate is 2/3 miles per hour

well first off u wrote on the graph the slope is 6/4 (Δy/Δx = 6/4) so I have no clue how you got -3/5. Also, since the slope is positive, there is no reason the rate is negative.
