In the 2014 - 2015 season of the English Premier League, there were 20 soccer teams, and each team played a
total of 38 matches. The scatter plot below shows the average number of goals each team scored per match, and
how many total matches each team won. Each dot on the scatter plot represents a team. A line was fit to the
data to model the relationship between scoring goals and winning games.

Step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
