Two friends are saving money to buy a video game. Friend A saves $10 a week, while Friend B saves $15 a week. Write the equations for the total savings of each friend after w weeks. What are the slopes and y-intercepts of both equations?

Friend A: slope = 10, y-intercept = 5; Friend B: slope = 15, y-intercept = 5

Friend A: slope = 5, y-intercept = 0; Friend B: slope = 10, y-intercept = 0

Friend A: slope = 20, y-intercept = 0; Friend B: slope = 15, y-intercept = 10

Friend A: slope = 10, y-intercept = 0; Friend B: slope = 15, y-intercept = 0

A school is selling tickets for a play. The tickets cost $8 each, and there is a one-time fee of $50 for the venue. Write the equation for the total revenue (R) in terms of the number of tickets sold (n). What is the slope and y-intercept?

R = 8n; Slope: 8, Y-intercept: 0

R = 50n + 8; Slope: 50, Y-intercept: 8

R = 8n + 50; Slope: 8, Y-intercept: 50

R = 10n + 50; Slope: 10, Y-intercept: 50
