You can put this solution on YOUR website!
Finding the X and Y intercepts of 8X - 6Y = -24
\n" ); document.write( "Two rules
\n" ); document.write( "the x intercept occurs when y = 0, to find x intercept, substitute 0 for y
\n" ); document.write( "8x - 6(0) = -24
\n" ); document.write( "8x + 0 = -24
\n" ); document.write( "x = -24/8
\n" ); document.write( "x = -3 is the x intercept
\n" ); document.write( "and
\n" ); document.write( "the y intercept occurs when x = 0, to find the y intercept substitute 0 for x
\n" ); document.write( "8(0) - 6y = -24
\n" ); document.write( "0 - 6y = -24
\n" ); document.write( "y = -24/-6
\n" ); document.write( "y = +4
\n" ); document.write( ":
\n" ); document.write( "You can confirm this graphically, put the equation into the slope intercept form and plot it
\n" ); document.write( "8x - 6y = - 24
\n" ); document.write( "-6y = -8x - 24
\n" ); document.write( "y has to be positive, mult by -1
\n" ); document.write( "6y = 8x + 24
\n" ); document.write( "divide by 6
\n" ); document.write( "y = $\"8%2F6\"$ x + 4
\n" ); document.write( "plot this equation and it will look like this
\n" ); document.write( " $\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-4%2C+6%2C+%288%2F6%29x%2B4%29+\"$
\n" ); document.write( "note that the graph intercepts the x axis at -3 and the y axis at + 4
\n" ); document.write( " \n" ); document.write( "

\n" );
