X + x + 1 = -249
2x = -250
x = -125
-125 + 1 = -124
The numbers are -125 and -124
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.
You multiply 8.5 by 5.25 by 4 and get 178.5
x = -1
y = 1
To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:
1 - Search for the points in which the line crosses the x and or y axis.
2 - Hit 2nd Graph to access the table and find when x and y equal zero.
Hope this helps!
