The ordered pair to complete is not included...
To complete the ordered pair, take the given number, let's say it is (?, 3): x = ?, y = 3
Start by substituting it in for y, and solve for x
y = 4 - 5x (rearranged to slope-intercept form for simplicity)
3 = 4 - 5x
-1 = -5x
x = 1/5 = .2
The completed pair is now: (.2, 3)
For another example, let's take the given number as (8, ?), x = 8, y = ?
y = 4 - 5x
y = 4 - 5 x 8
y = 4 - 40
y = -36
(8, -36)

What is the ordered pair that is the solution to these equations 3x - 2y equals 8 2x plus 5y equals -1?
y=(-1) x=(2)
Which ordered pair is a soultion of the linear system 15x plus 8y equals 6 and 25x plus 12y equals 14?
x = 2 and y =-3 so the lines intersect at (2, -3)
Complete the ordered pair so that it is a solution of x plus y - 1 equals 0?
Although no incomplete ordered pairs have been shown they can be readily solved.If x + y - 1 = 0, then x = 1 - y, also y = 1 - x.From the above formulae for x and y then any omissions can be completed.EXAMPLE : complete the ordered pairs (1) (7, y) and (2) (x, -4)(1) y = 1 - x = 1 - 7 = -6 : The ordered pair is thus (7, -6)(2) x = 1 - y = 1 -(-4) = 5 : The ordered pair is thus (5, -4)
Solve the system of equations enter your answer as an ordered pair 6x - y equals 33 6x plus 3y equals 45?
It works out that x = 6 and y = 3 or as (6, 3)
What (1 0) is an ordered pair of the function f(x) 1 plus x. true or false?
