You can put this solution on YOUR website!
y = mx + b is the template for the slope-intercept
\n" ); document.write( "m = slope
\n" ); document.write( "b = y-intercept, which is the point (0,b)
\n" ); document.write( "The x-intercept is the point where y=0, which is (x,0).
\n" ); document.write( ".
\n" ); document.write( "1) y = x + 3
\n" ); document.write( ".
\n" ); document.write( "slope = 1
\n" ); document.write( "y-intercept = (0,3)
\n" ); document.write( "x-intercept = (=3,0)
\n" ); document.write( "With these two points, you can draw a line.
\n" ); document.write( ".
\n" ); document.write( "2) y = -2x-7
\n" ); document.write( ".
\n" ); document.write( "slope = -2
\n" ); document.write( "y-intercept = (0,-7)
\n" ); document.write( "x-intercept = (-7/2,0)
\n" ); document.write( ".
\n" ); document.write( "3) 2x + 3y = 9
\n" ); document.write( ".
\n" ); document.write( "3y = -2x +9
\n" ); document.write( "y = -2/3x + 3
\n" ); document.write( ".
\n" ); document.write( "slope = -2/3
\n" ); document.write( "y-intercept = (0,3)
\n" ); document.write( "x-intercept = (9/2, 0)
\n" ); document.write( ".
