Joe is going to travel to Dallas. He lives 320 miles away and can average 69 miles per hour. Use an equation to represent the distance D from Dallas in terms of h, the number of hours Joe has traveled. a. D = 69h c. D = 320 + 69h b. D = 320 - 69h

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.
