complete the following ordered pairs for the equation 2x-5y=17 (1,_) (_,-1) (-4,_)

2x-5y = 17. To complete the ordered pairs which satisfy
the equation: (1, ...), (..., -1) , (-4 , ...)

We
substitut  the one coordinate inthe respective variable  of the equation and solve for
the other variable.

(1 , ... ) : We substitute x = 1 , in
2x-5y=17 and find the y vaue:

2*1-5y = 17. Or -5y =17-2 = 
15. Or y = 15/-5 = -3

(... ,
-1): We substitute y = -1 in 2x-5y = 17 and solve for x: (2x-5(-1) = -19. So 2x  +5 =
17. Or 2x = 17-5 = 12. Or x = 12/2 =
6.

((-4, ...): To find the
missing y coordinate  we put x = -4 in 2x-5y = 17 and solve for x. 2(-4)-5y = 17. Or
-8-5y = 17. Or -5y = 17+8=25. Or y = 25/-5 =
-5.
