\n" );
document.write( "I am trying to graph an absolute value equation and cannot seem to solve it.
\n" );
document.write( "the equation is to Solve |2x+2|=-2/3x+2 Graphically.
\n" );
document.write( "In my answer booklet it says the 2 answer to this absolute value equation is x=-3 and x=0 but when I plot these two equations i notice that they both have a y intercept of 2 so, i thought that they would meet at x=2. Please help me, it would be greatly appreciated! Best of Luck. \n" );

Algebra.Com's Answer #440954 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! First of all, please put fractions which are factors in parentheses. The right side, as you posted it, means: \n" ); document.write( " \n" ); document.write( "It was only your mention that the y-intercept was 2 that allowed me to figure out that it was supposed to be: \n" ); document.write( " \n" ); document.write( "description that the At the y-intercept of 2, the y-coordinate is 2. The x-coordinate on the y-axis is always 0. This explains the x=0 solution. \n" ); document.write( "As for the other solution... \n" ); document.write( "The graphs of equations of the form: \n" ); document.write( "y = | mx+b | \n" ); document.write( "will \"bounce\" off the x-axis. They will \"bounce\" at the point whose x-coordinate is the number that makes mx+b be zero. For y = | 2x+2 |, the graph will \"bounce\" off the x-axis at -1 because -1 makes 2x+2 be zero. (If you can't see this, just set 2x+2 = 0 and solve for x.) \n" ); document.write( "The graph of y = | mx + b | will be the graphs of two \"half-lines\" which meet at the \"bounce\" point. One \"half-line\" will the part of the graph of y = mx+b that is above the x-axis and the other \"half-line\" will the the part of the graph of y = -(mx+b) (or y - -mx-b) which is above the x-axis. \n" ); document.write( "For y = | 2x+2 |, the two \"half-lines\" would be: y = 2x+2 and y = -2x-2. The first \"half-line\" is the one whose y-intercept is 2 and intersects \n" ); document.write( "Here's a graph of both y = | 2x+2 | and \n" ); document.write( " |
