determine the equation of each line:

a) slope 3.4 passing through point (-2, -4)
b) slope -5 and y-intercept -0.7

  • math -

    a. m = 3.4, P(-2,-4).
    Y = mx + b.
    3.4*(-2) + b = -4
    -6.8 + b = -4
    b = 2.8 = y-int.
    Eq: Y = 3.4x + 2.8.

    b. m = -5, y-int = -0.7.
    Y = mx + b.
    Eq: Y = -5x - 0.7.
