Question

Calculate the slope m, if defined, of the straight line through the given pair of points. Try to do the problem without writing anything down except the answer. (If an answer is undefined, enter UNDEFINED.) (10, −5.5) and (0, −1.5)

Answer 1

(10,-5.5)(0,-1.5)
slope = (-1.5 - (-5.5) / (0 - 10) = -4/10 which reduces to - 2/5
