find the x and y intercept and graph the equation plotting the intercepts. please show all work. -5x+8y=-40
\n" ); document.write( "**
\n" ); document.write( "standard form of equation for a straight line: y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "for given equation:
\n" ); document.write( "-5x+8y=-40
\n" ); document.write( "8y=5x-40
\n" ); document.write( "divide by 8
\n" ); document.write( "y=5x/8-40/8
\n" ); document.write( "y=5x/8-5
