Answer:
Step-by-step explanation:
An ordered pair is a pair of coordinates on a graph that satisfy a particular equation.
From our question, the given equation is
4x + 5y = 2017
5y = 2017 - 4x
y = (2017 - 4x) / 5
but (x,y) are positive integers meaning that x and y > 0
when x = 1, y = (2017 - 4) /5
y = 2013/5
=402.6
Hence (x.y) = (1. 402.6) which is not a solution to the equation
when x = 2 , y = (2017 -8) /5
y = 2009/ 5 = 401.8
(x,y) = (2, 401.8) which is not a solution to the equation
when x = 3 , y = (2017 - 12)/ 5
y = 2005/5 = 401
(x, y) = (3, 401) which is a solution to the equation
when x =5 , y = (2017 - 20) / 5
y = 1997/5 = 399.4
(x,y) = (5, 399.4) which is not a solution to the equation
