\n" ); document.write( "The upper right corner is the first quadrant where x and y are both positive, y being vertical from the horizontal line, x being along the line.
\n" ); document.write( "The upper left is the second quadrant, where x is negative but y is positive
\n" ); document.write( "The lower left is the third quadrant, where x and y are both negative
\n" ); document.write( "The lower right is the fourth quadrant, where x is positive and y is negative.
\n" ); document.write( "Slope is the change in vertical nature of the line. It is the change in y over a certain region divided by the change in x.
\n" ); document.write( "Here, the y value goes up 1 unit (positive) for every 1 unit to the right (x, positive), so the slope is 1.
\n" ); document.write( "One can take the slope of a line by looking at any two points.
\n" ); document.write( "(x,y). (2,4) and (3,9) have a slope of (9-4)/(3-2) OR (4-9)/(2-3)=5 in both instances. The y changes have to be done in the same order as the x-changes. \n" ); document.write( "
