There are 221 students on a field trip. Five students ride in a van. The rest of the students fill 6 buses. Which equation can be solved to find the number of students, s, that are on each bus?

• 6s = 221

• 6s = 221 - 5

• s = 221 - 5

• s = 221 / 6

Andrea says that a system of two linear equations must have at least one solution as long as the lines have different y-intercepts. For example, the equations y = 2x + 4 and y = 4x - 6 have different y-intercepts and have a solution at (5, 14). Select the pair of linear equations that can be used to disprove Andrea’s claim.

• A. y = -2/3x + 4 and y = 3/2x - 4

• B. y - 2x = 4 and 4y - 8x = 16

• C. y + 4x = 1 and y + 4x = 3

• D. y = 5/3x + 3/5 and y = 3/5x + 5/3
