\n" ); document.write( "x = number of books rented
\n" ); document.write( "Each book costs $1 to rent, so this is the extra cost on top of the $10 pass.
\n" ); document.write( "The total cost would be x+10 dollars.
\n" ); document.write( "The equation is y = x+10 where y is the total cost.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It is of the form y = mx+b aka slope-intercept form
\n" ); document.write( "m = 1 = slope
\n" ); document.write( "b = 10 = y intercept\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The slope is the extra cost per book rented
\n" ); document.write( "The y intercept is the starting cost. It's the amount paid even if you rented 0 books.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug in x = 15 to find the value of y
\n" ); document.write( "y = x+10
\n" ); document.write( "y = 15+10
\n" ); document.write( "y = 25
\n" ); document.write( "It costs $25 if you rented 15 books.
\n" ); document.write( " \n" ); document.write( "
\n" );
