you put the fraction in simplest form (the numerator and denominator have no common factors besides one)
then you find what number your variable should be to make the denominator 0. this is excluded value b/c your denominator can never equal 0
the number you found is your excluded value
ex.
4
------ Your excluded value is 3 because 3(3-3)=0
x(x-3)

What is shown on a line graph?
The values for two variables plotted on two axes
What kind of relationship exists between the variables if your r value is close to plus 1?
When r is close to +1 the variables have a positive correlation between them; as the x-values increase, the corresponding y-values increase. There is also a strong linear correlation or relationship between the variables, when the value of r is close to +1.
