Replace x in the equation with the x value of the point (6) and solve. If it equals the y value (0) it is a solution if it noes not equal (0) it is not a solution.
Y = 6^2 = 36
36 is not 0 so (6,0) is not a solution
A B and D
A & D are known as irregular polygons
100 is the easiest because 1/100 =0.01
33/100=0.33
In simplified form it is 5x+5
