Algebra.Com's Answer #321677 by Theo(13342)![]() ![]() You can put this solution on YOUR website! equation is 3x - 2y = 6x - 3y + 4 \n" ); document.write( "standard form of the equation is ax + by = c \n" ); document.write( "subtract 6x from both sides of the equation to get: \n" ); document.write( "-3x - 2y = -3y + 4 \n" ); document.write( "add 3y to both sides of the equation to get: \n" ); document.write( "-3x + y = 4 \n" ); document.write( "the equation is now in standard form. \n" ); document.write( "a = -3 \n" ); document.write( "b = 1 \n" ); document.write( "c = 4 \n" ); document.write( "slope intercept form of the equation is y = mx + b where m is the slope and b is the y intercept. \n" ); document.write( "add 3x to both sides of the equation of -3x + y = 4 to get: \n" ); document.write( "y = 3x + 4 \n" ); document.write( "the equation is now in slope intercept form. \n" ); document.write( "m = slope = 3 \n" ); document.write( "y intercept = value of y when x is equal to 0 = 4 \n" ); document.write( "graph of y = 3x + 4 is shown below: \n" ); document.write( " \n" ); document.write( "you can plot the values of y for x = 0,1,2 from either the slope intercept form of the equation or the standard form of the equation. \n" ); document.write( "the slope intercept form is easier since it has already solved for y in terms of x. \n" ); document.write( "when x = 0, y = 4 \n" ); document.write( "when x = 1, y = 7 \n" ); document.write( "when x = 2, y = 10 \n" ); document.write( "working from the standard form of the equation, you'll get the same answer. \n" ); document.write( "for example: \n" ); document.write( "when x = 2, the standard form of the equation of -3x + y = 4 becomes -6 + y = 4 which becomes y = 10 after you add 6 to both sides of the equation. \n" ); document.write( "the original form of the equation should also get you the right answer if you converted everything correctly. \n" ); document.write( "the original form of the equation is -3x - 2y = -3y + 4 \n" ); document.write( "replacing x with 2, you get: \n" ); document.write( "-6 - 2y = -3y + 4 \n" ); document.write( "add 6 to both sides of the equation to get -2y = -3y + 10 \n" ); document.write( "add 3y to both sides of the equation to get y = 10 \n" ); document.write( "when x = 2, y = 10. \n" ); document.write( "all forms of the equation get you the same value of y for the same value of x as they should. \n" ); document.write( " \n" ); document.write( " |
