Find the x-intercept and y-intercept of 2x+3y=-18. Thankyou\r
\n" ); document.write( "\n" ); document.write( "x-intercept or horizontal intercept is when the line crosses the x-axis,
\n" ); document.write( "in other words when y=0
\n" ); document.write( "y-intercept or vertical intercept is when the line crosses the y-axis,
\n" ); document.write( "in other words when x=0 or the point (0,b) where b is the y-intercept\r

\n" ); document.write( "3y = -2x - 18
\n" ); document.write( "y = (-2/3)x - 6
\n" ); document.write( "your slope m is -2/3
