Well, you have the correct equation in the slope-intercept form:
\n" ); document.write( "\"y+=+%28-3%2F4%29x%2B8\"
\n" ); document.write( "The slope is \"-3%2F4\" and, of course, slope is rise over run, so the rise is 3 and the run is 4.
\n" ); document.write( "The question of which part of the slope is negative is really irrelevant. The entire slope is negative which means that the line leans to the left.
\n" ); document.write( "One way to look at it is in drawing the line so that is has the correct slope, you would go up (rise) 3 units on the graph and then go left (run) -4 units. Why left and not right? Well, because the slope is negative (left-leaning) and not positive (right-leaning).
