in the coordinate plane , points ( x , 2 ) and ( 4 , y ) are on line k . if line k passes through the origin and has slope 1 / 4 , then x - y =
"line k passes through the origin and has slope 1 / 4 means that its equation is y = 1 / 4 * x . thus : ( x , 2 ) = ( 8 , 2 ) and ( 4 , y ) = ( 4,1 ) - - > x - y = 8 - 1 = 7 . answer : b"
multiply(multiply(4, 4), divide(2, 4))
