Using the distance formula, we get d = sqrt( (x2-x1)^2 + (y2-y1)^2 ) d = sqrt( (1-(-3))^2 + (-3-3)^2 ) d = sqrt( (1+4)^2 + (-3-3)^2 ) d = sqrt( (4)^2 + (-6)^2 ) d = sqrt( 16 + 36 ) d = sqrt( 52 ) d = 7.21110255 *** see note below *** d = 7.21
Note: Use a calculator with a square root function. The value is approximate.
