The cost in dollars, y, to participate x days in a bike tour is a linear function. Lou's bike tour is described by the equation y = 6x + 40. The cost of Mary's
bike tour is $120 for a 14-day bike tour. If both Lou and Mary take 14-day
tours, whose bike tour costs less? *

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

Find the equation of a line that is perpendicular to line g that contains (p, q). coordinate plane with line g that passes through the points negative 3 comma 6 and 0 comma 5 3x − y = 3p − q 3x + y = q − 3p x − y = p − q x + y = q − p
