Plug any number in for x and find the resulting y, then if you need to graph place the coordinate points on the plane. For example if you set x=2 the equation becomes y=0.5(2). From here we can see 0.5(2)=1 and this is equal to 1 so in a data chart you would write under x the number 1 and under y the number 2.
Answer: Domain is {2,5,0,1}
7 and 7/8=63/8 and 3 and 1/4=13/4. 63/8 and 13/4 as common denominators are 63/8 and 26/8. 63/8-26/8=37/8. 37/8 as a mixed number is 4 5/8.
