(consider the following system of equations: y = −x + 2 y = 3x + 1 which description best describes the solution to the system of equations?
line y = −x + 2 intersects line y = 3x + 1. lines y = −x + 2 and y = 3x + 1 intersect the x-axis. lines y = −x + 2 and y = 3x + 1 intersect the y-axis. line y = −x + 2 intersects the origin.

1foot = 12 inches; 1 yard = 3 feet

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
