Given the equation is 3x-4y-8=12(add 8 on both sides)3x-4y=20We plug in each point into the equation and check which one satisfies the equation .(0,-5) -------->3(0)-4(-5)=20 => 20 =20 . It is true(4,-2)------->3(4)-4(-2)=20 => 20 =20 . It is true (8,2) ------->3(8)-4(2)=20 => 16 =20 . It is false (-16,-17) ------->3(-16)-4(-17)=20 => 20 =20 . It is true (-1,-8) ------->3(-1)-4(8)=20 => -35 =20 . It is false(-40,-34) ------->3(-40)-4(-34)=20 => 64 =20 . It is false(0,-5) (4,-2) and (-16,-17) satisfies the equation.As well (0,-5) (4,-2) and (-16,-17) are our solutions
