Use DE←→ and FG←→ to answer the question.

DE←→ contains the points D(1,−2) and E(3,4).
FG←→ contains the points F(−1,2) and G(4,0).
Is DE←→ perpendicular to FG←→? Why or why not?

Yes, because the product of the slopes is 1.
No, because the product of the slopes is not −1.
No, because the product of the slopes is not 1.
Yes, because the product of the slopes is −1.

  3. So, you guessed twice. That's not the same as solving the problem.
    DE has slope (4+2)/(3-1) = 4
    FG has slope (0-2)/(4+1) = -2/5
    since 4 * -2/5 ≠ the lines are not perpendicular ... (B)

  4. slope of ED = (4+2)/(3-1) = 3
    slope of FG = (0-2)/(4+1) = -2/5

    For 2 lines to be perpendicular the product of their slopes must be -1

    So what is your conclusion ?
