I have not been able to graph linear equations. Can someone please tell me how to enter this equation properly into my calculator? I have solved the problem manually. \r

y = mx+b, where x and y are the coordinates (y goes up and down, x horizontally)
\n" ); document.write( "3x+4y = -16
\n" ); document.write( "4y = -3x-16
\n" ); document.write( "y = -3x/4-4
\n" ); document.write( "Choose 0 to substitute for x:
\n" ); document.write( "y = -3(0)/4-4
\n" ); document.write( "y = 0/4-4
\n" ); document.write( "y = 0-4
\n" ); document.write( "y = -4 We now have one set of points: (0, -4)
\n" ); document.write( "Now choose 1 to substitute for x:
\n" ); document.write( "y = (3(1)/4)-4
\n" ); document.write( "y = 3/4-4
\n" ); document.write( "y = 3/4+-(4/1*4/4) - multiply to get a common denominator 4
\n" ); document.write( "y = 3/4-16/4
\n" ); document.write( "y = (3-16)/4
\n" ); document.write( "y = -13/4 now we have another set of points: (1,-13/4)
\n" ); document.write( "Try substituting 2 for x and you'll get a third set of points: (2,-5/2)
\n" ); document.write( "Now you have three ordered pairs you can graph:
\n" ); document.write( "(0, -4), (1, -13/4), (2, -5/2)
\n" ); document.write( "This is what you get:
