Do the points lie on the same line? Explain your answer. P(3.9), Q(-3,-9), R(0,0)
Choose the correct answer below.
O A. The slopes of all three pairs of coordinates are equal. Therefore, the points do not lie on the same line.
OB. The slopes of all three pairs of coordinates are not equal. Therefore, the points do lie on the same line.
O C. The slopes of all three pairs of coordinates are equal. Therefore, the points do lie on the same line.
OD. The slopes of all three pairs of coordinates are not equal. Therefore, the points do not lie on the same line.
