Use the graph to answer the question. On a coordinate plane, a line goes from (negative 5, 7) to (3, 3).

Which parametric equations describe the curve?

x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6

x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3

x = 0.5t + 4 and y = –t + 1 when –2 ≤ t ≤ 6

x = 0.5t + 4 and y = –t + 1 when –5 ≤ t ≤ 3

Luke started a weight-loss program. the first week, he lost x pounds. the second week, he lost pounds less than times the pounds he lost the first week. the third week, he lost 1 pound more than of the pounds he lost the first week. liam started a weight-loss program when luke did. the first week, he lost 1 pound less than times the pounds luke lost the first week. the second week, he lost 4 pounds less than times the pounds luke lost the first week. the third week, he lost pound more than times the pounds luke lost the first week.
