  • You can use the Pythagorean theorem. Plot the points and draw a triangle. The triangle will have two sides 5 and 6 units long, the hypotenuse will be the distance between the two points.

    5² + 6² = 61

    The square root of 61 is approximately equal to 7.8.

  • the formula for the distance between two points is d= the square root of (x1-x2)squared +(y1-y2)squared(sorry couldn’t figure out how to type that on my key board). 36+25=61. the square root of 61 is 7.8

  • Use the area formula: d = sqrt((x1 – x2)^2 + (y1 – y2)^2) (x1, y1) = (-3, 2) (x2, y2) = (5, -6) d = sqrt((-3 – 5)^2 + (2 – (-6))^2) d = sqrt((-8)^2 + (8)^2) d = sqrt(sixty 4 + sixty 4) d = sqrt(128) d = 8sqrt2 d = 8(a million.40-one) d = 11.3

  • i think the distance formula is sqrt( (x1-x2)^2 + (y1-y2)^2)

    so sqrt( (8-3)^2 + (2-8)^2)

    sqrt (25 + 36)

    sqrt61

    7.8

  • 7.8 ~~~~~~~~~~~answer

    Sqrt(61) = 7.81024968 (approx)
