There are many ordered pairs for that equation (an infinite number, really).
\n" ); document.write( "An ordered pair for such an equation is written as two numbers separated by a comma, and the whole thing wrapped in brackets. The first number is a value for x; the second number is the corresponding value for y.
\n" ); document.write( "One ordered pair for that equation could be (1,11). Another pair could be (5,51).
\n" ); document.write( "That equation represents a relation between two quantities represented by x and y.
\n" ); document.write( "The variable x could be the number of weeks since you opened a checking account started with a $1 deposit, and y could the balance in that account.
\n" ); document.write( "We like to graph relations, and y = 10x + 1 would be graphed as the slanted line below.
\n" ); document.write( " $\"graph%28300%2C300%2C-1%2C4%2C-5%2C45%2C10x%2B1%29\"$
\n" ); document.write( "The location of each point in that graph is represented by an ordered pair pair (x,y).
\n" ); document.write( "To graph the relation, you make a table of values for x and y. You could chose values for one variable, then calculate the corresponding value for the other variable.
\n" ); document.write( "It could look like this:
\n" ); document.write( " $\"matrix%282%2C7%2Cx%2C0%2C1%2C2%2C3%2C4%2C5%2Cy%2C1%2C11%2C21%2C31%2C41%2C51%29\"$ . \n" ); document.write( "
