find all points having an x-coordinate of 4 whose distance from the point (1,5) is 5

  1. Ben

    Use the distance formula.

  2. Bri

    which is?

  3. Ben

    It should be on your formula sheet if not then look it up.

  4. Steve

    you know that all points at a distance 5 will form a circle with center at (1,5) and radius 5. So,

    (x-1)^2 + (y-5)^2 = 25

    So, plug in x=4 and you have

    3^2 + (y-5)^2 = 25
    (y-5)^2 = 16
    y-5 = ±4
    y = 9 or 1

    So, the points are (4,9) and (4,1)

    Thanks Steve!
