Question 184871
x-2y=4  ( ,-3) (-4, )

For ( ,-3), y=-3 with x as unknown. Using the equation x-2y=4,
__
:: x-2(-3)=4
:: x-(-6)=4
:: x+6=4
:: x=-2 :: Therefore, the point is (-2,-3)

For (-4, ), x=-4 with y as unknown. Using the equation x-2y=4,
__
:: -4-2y=4
:: -2y=8
:: y=-4 :: Therefore, the point is (-4,-4)
