You can put this solution on YOUR website!
I think you meant to type Y = 4/5X - 10
\n" ); document.write( "--------------------
\n" ); document.write( "The standard eqaution of a line is Y = mX = b
\n" ); document.write( "Where m is the slope and b is the Y-intercept.
\n" ); document.write( "So yes, (0,-10) is the Y-intercept.
\n" ); document.write( "--------------------
\n" ); document.write( "The X intercept is found when Y is equal to zero.
\n" ); document.write( "\"0+=+%284%2F5%29X+-+10\"
\n" ); document.write( "Add 10 to both sides
\n" ); document.write( "\"10+=+%284%2F5%29X\"
\n" ); document.write( "Multiply both sides by 5/4
\n" ); document.write( "\"%285%2F4%29%2A10+=+cross%28%285%2F4%29%2A%284%2F5%29%29%2AX\"
\n" ); document.write( "Simplify
\n" ); document.write( "\"highlight%2812.5+=+X%29\"
\n" ); document.write( "The x-intercept is (12.5,0)
\n" ); document.write( "\"graph%28300%2C300%2C-20%2C20%2C-20%2C20%2C%284%2F5%29x-10%29\"
\n" ); document.write( "
\n" );
