1.	ILLUSTRATIVE EXAMPLESCheck which o the following are solutions o the equation x-2y = 4 and which areEXAMPLE 1not:(iii)(4,0)(iv)(Q.4V2)bd(1,1)
Answer» ii) as 2 -0 is not equal to 4iv) as sqrt2 - 2× 4sqrt2 = - 7sqrt2 not equal to 4v) as 1-2 = -1 is not equal to 4 how 7 sqrt2 we get that because sqrt2 - 8sqrt2 = -7sqrt2

Answer»

ii) as 2 -0 is not equal to 4iv) as sqrt2 - 2× 4sqrt2 = - 7sqrt2 not equal to 4v) as 1-2 = -1 is not equal to 4

how 7 sqrt2

we get that because sqrt2 - 8sqrt2 = -7sqrt2
