There are infinitely many rules. SOme of these are:
y = x/80
y = 80/x
y = x + 79
y = 81 - x
y = sqrt(x+1) - 8
y = 1/2 x + 1
y = x(x + 1)
There is no specific rule. y = -sqrt(x) y = x - 12 y = -x/3 y = x2 - 84 are all possible.

The graph of y = x + 1 is a straight line with slope 1 which passes through the point (0, 1) If you have y < x + 1, then it is the area under the line y = x + 1 and is shown by shading the area under the line. If you have y > x + 1, then it is the area above the line y = x + 1 and is shown by shading the area above the line.
y = x/3
-81
Let the number by 'm' & 'n' Hence mn = 80 (product) m + n = 21 (sum) Hence m = 21 -b Substitute (21 - n)n = 80 21m - n^(2) = 80 n^(2) - 21n + 80 = 0 Factor (n - 16)(n - 5) = 0 Hence n= 16 & m = 5
y = 1/2 x + 1
There is no specific rule. Among the infinitely many possibilities are y = 5 (whatever x is) y = x + 4 y = 27x - 22 y = x2 + 4x y = 28x/4 - 2
y = x(x + 1)
(x' , y') = (-x + 1 , y + 4)
That's the function rule.
The rule for a set of ordered pairs is the statement that states the relationship of of a certain value to another value.For example:given the set of ordered pair { (1,2) , (3,4) , (5,6) , (7,8) }we notice that the value of y is increased by 1 as the value of x varies.For instance, in the first ordered pair which is (1,2) where 1 is x and 2 is y such that (x,y), 1 increased by 1. In other words, x is increased by 1.So we say that the rule of the ordered pair is:{(x,y) | y = x + 1 }read as "The set of ordered pairs such that y is equal to x plus one"
There is no specific rule. y = -sqrt(x) y = x - 12 y = -x/3 y = x2 - 84 are all possible.
