Find three ordered pair solutions of 5x 3y 15 solution 05

Find three ordered pair solutions of -5x + 3y = 15.

solution (0,5); (-3,0) the last solution is X=-2 the book give me the number I dont know if they guess or it is a way to find out

given that -5x + 3y = 15.

x = 0 then 0+3y=15 it given y=5

so one oder pair (0,5)

if y=0 then -5x+0=15

x=-3

second orered pair is ( - 3, 0)

if x=-2 then -5(-2)+3y = 15

10+3y = 15

3y = 5

y= 5/3

third ordered pair is (-2, 5/3)
