I think the answer is y=1/4x+2 :)
The number "R" could be "A" and "D" because the range is 14 it cant be "B" or "C"
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
D.2/5 because 3/5 are odd so the remaining 2 are even so 2/5 are not odd!
