I believe the coordinates of K are [tex](-\frac{1}{4},\frac{5}{8})[/tex]
the x is negative and the y is positive because it's on the second quadrant.
y = [tex]\frac{5}{8}[/tex] because it is closer to half than [tex]\frac{3}{4}[/tex] is
[tex]\frac{5}{8} = 0.625[/tex] and [tex]\frac{3}{4}= 0.75[/tex]
