64,000 attended the last NFL football game. 80% of the supporters in attendance were rooting for the home team, and 20% of the supporters in attendance were rooting for the away team. How many people were at the game to support the home team?

12800 People was supporting the home team!

64,000 - 80% = 12800

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
