The equation y = 7x represents a linear relationship where the value of y is always 7 times the value of x. Therefore, all ordered pairs for this equation will have y as a multiple of 7x. For example, when x = 1, y = 7; when x = 2, y = 14; and so on. The ordered pairs for y = 7x will be in the form (x, 7x).
There are many different ordered pairs for this. To figure it out, make up a value for x. Then plug it into the equation and solve to find y. You can use any number. For example, if x=2, then your equation would be 3(2)+1. Solve that and you get 7 for the answer (y). if x=2, then y=7 so one of the ordered pairs would be (2,7).
(-4 -2) (0 -3) (2 7) (1 4)
there is an infinte amount of ordered pairs in this equation a few examples could be... (1,-3) (2,-13) (3,-23) (234652,-2346513) (-25,257)
In general to work out the slope it is: (y1-y2)/(x1-x2) whereas x and y are a pair pf coordinates
There are an infinite number of ordered pairs. (-5, -7) is one pair
(6,6) (0,0) (4,4) etc
Any set of ordered pairs. {(0,0),(2,3),(2,-7)} is a relation.
(7, 6) and (14, 12) are two obvious candidates.

(7,-3),(-4,2),(-1,0),(2,-4)(0,-6) What is the domain and range of the set of ordered pairs? Check all that apply
Use this cordinate ,find the other cordinate that makes the ordered pair a solution of the given equation: x+4y=7,(_,3)

The ordered pair (0, -6) Ordered pairs look like (x, y). they are the coordinates of a point on your graph. Asking if (0,6) is a solution to your equation means, does this point lie on the graph? Or algebraically, if you substitute in x = 0 and y = -6 into the equation, does it work? y = 5x-7 -6 = 5(0) -7 -6 = 0 - 7 -6 = -7 Well, -6 does NOT = -7, so we know that this ordered pair is not a solution to the function.
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)
