Tell the answer to, or how to put, y=-3/2x+4 -into standard form\r
\n" ); document.write( "\n" ); document.write( "The slope-intercept form is \"y+=+mx+%2B+b\" in which m and b are constants, in which m is the slope of the graph and b is the value where the graph intercepts the y-axis.\r
\n" ); document.write( "\n" ); document.write( "So what you need to do for the first problem is to move the terms around and solve for y to get the equation to match the slope intercept form.\r
\n" ); document.write( "\n" ); document.write( "\"4x+-+5y+=+10\"\r
\n" ); document.write( "\n" ); document.write( "Move the 4x term to the right side of the equation, by subtracting 4x from both sides. This subtraction cancels out the 4x on the left side and makes a -4x appear on the right side as follows:\r
\n" ); document.write( "\n" ); document.write( "\"++-5y+=+-4x+%2B+10\"\r
\n" ); document.write( "\n" ); document.write( "Now divide all terms on both sides of the equal sign by -5 to get:\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%28-4%2F-5%29x+%2B+10%2F-5\"\r
\n" ); document.write( "\n" ); document.write( "When you divide -4 by -5 the answer becomes positive. And dividing +10 by -5 results in -2. So the answer becomes:\r
\n" ); document.write( "\n" ); document.write( "\"y++=+%284%2F5%29x+-+2\"\r
\n" ); document.write( "\n" ); document.write( "The next problem involves putting an equation into standard form. The standard form is:\r
\n" ); document.write( "\n" ); document.write( "\"ax+%2B+by+=+c\"\r
\n" ); document.write( "\n" ); document.write( "where a, b, and c are all constants. So what you need to do is take the equation you are given, an equation in slope-intercept form, and rearrange things to get it into standard form. You are given:\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%28-3%2F2%29x%2B4\"\r
\n" ); document.write( "\n" ); document.write( "Get rid of the denominator of 2 by multiplying all the terms in this equation by 2 to get:\r
\n" ); document.write( "\n" ); document.write( "\"2y+=+-3x+%2B+8\"\r
\n" ); document.write( "\n" ); document.write( "Next, move the -3x term to the other side of the equal sign by adding 3x to both sides. Adding +3x to the right side cancels the -3x. And adding 3x on the left side makes a +3x appear on the left side. The result is:\r
\n" ); document.write( "\n" ); document.write( "\"%2B3x+%2B+2y+=+8\"\r
\n" ); document.write( "\n" ); document.write( "This is the standard form that you are looking for.\r
\n" ); document.write( "\n" ); document.write( "Hope this helps.
