An extension of the Pythagorean Theorem results in what is the so-called "distance formula".
d^2=(x2-x1)^2+(y2-y1)^2, in this case you have points (-2,4) and (2,0) so:
d^2=(2--2)^2+(0-4)^2
d^2=4^2+(-4)^2
d^2=16+16
d^2=2*16
d=√32 units
d=√(2*16)
d=4√2 units
d≈5.66 units (to nearest hundredth of a unit)
1/4 is 0.25 as a fraction
Graph D, because no x-value repeats and it passes the vertical line test.
She brings 3 donuts because a dozen is 12 and 1/4 of 12 is 3.
