(0, 1) (4, -2)
(-2 - 1)/(4 -0) = -3/4
From the pie chart described, the percent of people that responded that football was their favorite sport to watch is 42% which represents 210 of the people surveyed.
Let the number of people surveyed be x, then

Therefore, the number of people surveyed is 500 people.
X = -4
the slope is undefined as it only passes through the x-axis on -4.
That would be 5, all you need to do is divide by 2 or mltiply by 0.5 to get half of a number
