The first soccer team scored 8 goals in 4 games which most likely means they scored 2 goals every game and the second soccer team scored 27 goals in 9 games, which most likely means they scored 3 goals every game. Therefore the second soccer team scored more goals per game. I hope this helped :D
Slope is basically rise over run. Looking at the graph you see it rises one unit and then goes over to the left by one unit. 1÷1 equals 1 so That is your slope.
