In Exercises 1 and 2, determine which of the lines, if any, are parallel. Explain. 1. Line a passes through (-1, 1) and (1, 3). 2. Line a: 2y = x + 12
Line b passes through (3, 4) and (0, 2). Line b: 2y - x = 5
Line c passes through (0, 1) and (3, 3). Line c: 2y + x = 4

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
