    Equation of a Line

    - Distance & Midpoint

    Choice C
    15. The straight-line distance, in miles, from Marville to Bright City must be:

    Distance between two points P(x1, y1) and Q(x2, y2) is given by:

    d(P,Q)=(x2−x1)2+(y2−y1)2

    Distance of a point P(x, y) from the origin is given by:

    d(0,P)=x2+y2

    Therefore,

    d(0,Bright City)=3002+1602=340

    which is between 300 and 390.
