\n" ); document.write( "\n" ); document.write( "If you want to find the equation of line with a given a slope of \"5%2F6\" which goes through the point (\"3\",\"4\"), you can simply use the point-slope formula to find the equation:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "---Point-Slope Formula---
\n" ); document.write( "\"y-y%5B1%5D=m%28x-x%5B1%5D%29\" where \"m\" is the slope, and is the given point\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So lets use the Point-Slope Formula to find the equation of the line\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y-4=%285%2F6%29%28x-3%29\" Plug in \"m=5%2F6\", \"x%5B1%5D=3\", and \"y%5B1%5D=4\" (these values are given)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y-4=%285%2F6%29x%2B%285%2F6%29%28-3%29\" Distribute \"5%2F6\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y-4=%285%2F6%29x-5%2F2\" Multiply \"5%2F6\" and \"-3\" to get \"-5%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=%285%2F6%29x-5%2F2%2B4\" Add 4 to both sides to isolate y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=%285%2F6%29x%2B3%2F2\" Combine like terms \"-5%2F2\" and \"4\" to get \"3%2F2\" (note: if you need help with combining fractions, check out this solver)\r

\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the equation of the line with a slope of \"5%2F6\" which goes through the point (\"3\",\"4\") is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y=%285%2F6%29x%2B3%2F2\" which is now in \"y=mx%2Bb\" form where the slope is \"m=5%2F6\" and the y-intercept is \"b=3%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice if we graph the equation \"y=%285%2F6%29x%2B3%2F2\" and plot the point (\"3\",\"4\"), we get (note: if you need help with graphing, check out this solver)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " Graph of \"y=%285%2F6%29x%2B3%2F2\" through the point (\"3\",\"4\")\r
\n" ); document.write( "\n" ); document.write( "and we can see that the point lies on the line. Since we know the equation has a slope of \"5%2F6\" and goes through the point (\"3\",\"4\"), this verifies our answer.
