You can put this solution on YOUR website!
-x +2y = 7
\n" ); document.write( "2y = x + 7
\n" ); document.write( "y = x/2 + 7/2 = (1/2)*x + 7/2
\n" ); document.write( ".
\n" ); document.write( "Recall the slope-intercept form is: y = mx + b
\n" ); document.write( ".
\n" ); document.write( "m = slope = 1/2
\n" ); document.write( ".
\n" ); document.write( "b = y-intercept: (0, 7/2)
\n" ); document.write( ".
\n" ); document.write( "Set y=0 and find the x-intercept.
\n" ); document.write( ".
\n" ); document.write( "0 = (1/2)*x + 7/2
\n" ); document.write( "x = -7
\n" ); document.write( "(-7,0)
\n" ); document.write( ".
