Equation B: -2x - 8y = 8
Which statement is true about the values x= -2 and y = -0.5?
A. They are the only values that make both equations true.
B. They show that the equations represent the same line.
C. They satisfy equation A but not equation B.
D. They satisfy equation B but not equation A.

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
