Review some of the algebra tools you already have. Consider two line segments AB and CD, given A(0,8), B(9,2), C(1,3), and D(9,15). a. Draw these two segments on a coordinate grid. Find the length of each segment. b. Find the equation of line AB and the equation of line CD. Write both equations in y=mx+b form. c. Is AB//CD? Is AB⊥CD? Justify your answer. d. Use algebra to find the coordinates of the point where AB and CD intersect.
