Algebra.Com's Answer #37296 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! How do you solve y when doing this equation on a graph? (2x - 3y = 12) \n" ); document.write( "I'm not sure what you mean. I'm going to do this two ways. Maybe one of them is what you need. \n" ); document.write( "You can graph this by the intercept method. \n" ); document.write( "Let x=0 and solve for y: \n" ); document.write( "2(0)-3y=12 \n" ); document.write( "0-3y=12 \n" ); document.write( "-3y=12 \n" ); document.write( "-3y/-3=12/-3 \n" ); document.write( "y=-4 \n" ); document.write( "Plot (0,-4) \n" ); document.write( "Let y=0 and solve for x: \n" ); document.write( "2x-3(0)=12 \n" ); document.write( "2x-0=12 \n" ); document.write( "2x=12 \n" ); document.write( "2x/2=12/2 \n" ); document.write( "x=6 \n" ); document.write( "Plot (6,0) \n" ); document.write( "Connect the dots and you have a line. \n" ); document.write( "---------------------------------------------------------- \n" ); document.write( "Another way to do this is to put the equation in slope intercept form, \n" ); document.write( "Solve the equation for y: \n" ); document.write( "2x-3y=12 \n" ); document.write( "-2x+2x-3y=-2x+12 \n" ); document.write( "0-3y=-2x+12 \n" ); document.write( "-3y=-2x+12 \n" ); document.write( "-3y/-3=-2x/-3+12/-3 \n" ); document.write( "y=(2/3)x-4 \n" ); document.write( "Plot (0,-4) \n" ); document.write( "Frome that point use the slope, m=rise/run=2/3 and go up 2 and right 3 and put another point at (3,-2) \n" ); document.write( "Connect the points and you should have a line that looks like: \n" ); document.write( " \n" ); document.write( "Happy Calculating!!! \n" ); document.write( " |
