You can put this solution on YOUR website!
The line containing (4,-2) and parallel to -5x+6y=-2 will have the same slope but a different constant.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Assuming you do not understand Standard Form, convert the given equation into slope-intercept form:
\n" ); document.write( "\"6y=5x%2B%28-2%29\"
\n" ); document.write( "\"y=%285%2F6%29x-2%2F6\"
\n" ); document.write( "\"y=%285%2F6%29x-1%2F3\"
\n" ); document.write( "... and the slope you want is \"highlight_green%28highlight_green%285%2F6%29%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let us put that back into the equation we want to find, and change back from slope-intercept form to standard form.
\n" ); document.write( "\"y=%285%2F6%29x%2Bb\", because at this point we do not know the y-intercept
\n" ); document.write( "\"y-%285%2F6%29x=b\"
\n" ); document.write( "\"-%285%2F6%29x%2By=b\"
\n" ); document.write( "\"-5x%2B6y=6b\",
\n" ); document.write( "This is back into standard form, but we want to know what is the value of 6b.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute the point which is supposed to be contained on this line, the given point (4,-2) and compute 6b. You do not need to solve for b here; you only want the value of 6b as the combined constant.
\n" ); document.write( "\"-5%284%29%2B6%28-2%29=6b\"
\n" ); document.write( "\"-20-12=6b\"
\n" ); document.write( "\"highlight_green%286b=-32%29\"
\n" ); document.write( "-
\n" ); document.write( "The use of \"b\" is for the y-intercept in the slope-intercept equation form. In this specific problem example, we need 6b for the standard form equation.
\n" ); document.write( "Finally our wanted equation is \"highlight%28-5x%2B6y=-32%29\".
\n" ); document.write( "
\n" );
