Which ordered pair would form a proportional relationship with the point graphed below?


On a coordinate plane, a line goes through points (0, 0), (10, 40) and (negative 10, negative 40).
(40, 10)
(–5, –10)
(5, 20)
(–10, –20)

Respuesta :

(5, 20) will form a proportional relationship with the point.

Given

A line passes through points (0,0) , (10,40) and (-10, -40)

slope of line is ( 40/10=4 ) and equation of line is ( y=4x )

                  (40, 10)

x=40 , y=160            Not proportional

                   (-5, -10)

x=-5 ,  y=-20             Not proportional

                   ( 5, 20 )

x= 5 ,   y=20             proportional

                    (-10,-20)

x= -10   y= -40          Not proportional

(5, 20) will form a proportional relationship.
