1. which graph models the equation y = 3.5x? 2. determine the equation of the line given by the graph. a)y = 3x + 2(wrong, i'm retaking the test) b)y = 3x − 2 c)y = 1/3x + 2 d)y = 1/3x − 2 3.determine the equation of the line given by the graph. a)y = 2/3x - 1 b)y = 3/2x - 1 c)y = -2/3x - 1(wrong, retaking) d)y = -3/2x - 1 4.determine the equation of the line given by the graph. a)y = 5/3x - 4 b)y = 3/5x - 4 c)y = -5/3x + 4 d)y = -3/5x + 4
