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, \"highlight%28y=mx%2Bb%29\", where m=slope and (0,b) is the y-intercept.
\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( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C%282%2F3%29x-4%29\"
\n" ); document.write( "Happy Calculating!!!
