Respuesta :

you can choose values of x and calculate , values of y
for example,
2y= x+1
y=(1/2)x +1/2

x=0,  y=(1/2)*0 +1/2 = 1/2                       point (0, 1/2)
x=3,  y=(1/2)*3+1/2=3/2+1/2=4/2=2      point (3, 2)

and so on
let x = 1:-

-(1) + 2y = 1
2y = 1 + 1 = 2
y = 1

so one ordered pair is (1, 1)
