You are going to the fair and have $16 to spend on rides and games. Ride tickets cost $4 and game tickets cost $2. The equation 4x + 2y = 16 models the situation, where x is the number of ride tickets you buy, and y is the number of game tickets you buy.
Find and interpret the intercepts
X intercept : x = 4 (4 rides and 0 games)
Y Intercept : y = 8 (0 rides and 8 games)
