- Q1A video streaming service charges a $25 initial fee and $8.99 per month. What is the equation?y = 8.99 + 25y = 25x + 8.99y = 8.99x + 258.99 = 25x30s
- Q2Which equation represents a proportional relationship?y = -15x + 5y = 15xy = 15y = 15x + 530s
- Q3Which equation represents a non-proportional relationship?y = 5/3xy = 5y = 5x + 3y = 5x30s
- Q4600,000 gallons of water pass through a given point along a river every minute. Which equation represents the amount of water, y, that passes through the point in x minutes?x = 10,000yy = 600,000xy = 600,000 + xy = 10,000x30s
- Q5At UPS, first-class letters cost $0.49 for the first ounce and $0.22 for each additional ounce. What is the equation for this situation? and is it proportional?y = 0.49 + 0.22x, Proportionaly = 0.22 + 0.49, Non-Proportionaly = 0.49 + 0.22x, Non-Proportionaly = 0.22 + 0.49x, Proportional30s
- Q6Ann's car can travel 228 miles on 6 gallons of gas. Write an equation to represent the distance y, in miles Ann's car can travel on x gallons of gas.y = 228 + 6y = 228xy = 38 + xy = 38x30s

- Q8What is the constant rate of change for the equation for y = .15 + 5x5.1530s
- Q9What is the y-intercept for the equation y = 6x - 26-2230s
- Q10What is the y-intercept for the equation y= 65 + 12x126530s
- Q11A pilot takes a taxi from the airport to a hotel. The taxi driver charges a $2.50 initial charge plus $2.65 per mile. Which equation matches the situation?y = 2.65x + 2.50y = -2.65x + 2.50y = 2.65 - 2.50y = 2.50x + 2.6530s
- Q12From a starting position at 7 meters below sea level, a fish is descending 3 meters per second. Which equation matches the situation?y = -7m -3y = 7-3y = -3m -7y = -7 + 3m30s
