What is a "Slope, Midpoint & Distance"? This is the problem:
(7,3) and (-1,-4)

  • Math 10th grade -

    slope = (Y2-Y1)/(X2-X1)
    =(-4-3)/-1-7
    = -7/-8
    =7/8

    midpoint
    x = X1 + (1/2)(X2-X1) = 7 +(1/2)(-8)
    = 7-4
    = 3
    do y the same way

    d^2 = (Y2-Y1)^2 + (X2-X1)^2
    d^2 = 49+64 = 113
    d = sqrt (113)
