Step-by-step explanation:
Given points ( 2 , 7) and ( - 8 , 1 )
Distance between two points





Therefore distance between two points is 4 units.
4y^2 - (-3y - (19y^2 - 4y)) - (5 + (-9y - 5)) =
4y^2 - (-3y - 19y^2 + 4y) -( 5 - 9y - 5) =
4y^2 - (-19y^2 + y) - (-9y) =
4y^2 + 19y^2 - y + 9y =
23y^2 + 8y <==
