The presented problem is in slope-intercept form: y = mx + b. \n" ); document.write( "m = slope \n" ); document.write( "b = y-intercept. \n" ); document.write( ". \n" ); document.write( "y = 8/3x +3 \n" ); document.write( ". \n" ); document.write( "slope = 8/3 \n" ); document.write( "y-intercept = 3 \n" ); document.write( ". \n" ); document.write( "which defines the point (0,3) \n" ); document.write( ". \n" ); document.write( "We know the slope = rise / run = change in y / change in x. \n" ); document.write( ". \n" ); document.write( "So for every change of 3 in x, we have a change of 8 in y. \n" ); document.write( ". \n" ); document.write( "That allows us to define another point: (0+3, 8+8) or (3,16) \n" ); document.write( ". \n" ); document.write( "You can graph the line using the two points, so pick the x-intercept as another. \n" ); document.write( "The x-intercept is where y=0. \n" ); document.write( "0 = 8/3x +3 \n" ); document.write( "-8/3x = 3 \n" ); document.write( "-8x = 9 \n" ); document.write( "x = -9/8 \n" ); document.write( "thus defining the point (-9/8,0) \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( " |
