a) Determine an equation for the line with slope 3 and passing through the origin.


b) What is an equation for the line perpendicular to the line in part a) that also passes through the point (0,2)?

  • math -

    a. Given: m = 3, P(0,0).

    Y = mx + b.
    0 = 3*0 + b
    b = 0.
    Eq: Y = 3x.

    b. m = -1/3, P(0,2).
    Y = mx + b.
    2 = (-1/3)*0 + b
    b = 2.
    Eq: Y = (-1/3)x + 2.
