Help meh pls i don't understand

a)

X = -3 , y = 0

x = -2 , y = 8

x = -1, y = 6

x = 0 , y = 0

x = 1 , y = -4

x = 2 , y = 0

x = 3 , y = 18

b)

x = 0 or 2

when x is equal to 2 or 0, y = 0.

(not sure about part be. But the equation will be true if x is equal to 2 or 0).

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
