You can put this solution on YOUR website!
First recall the slope-intercept form is: y = mx + b
\n" ); document.write( "f(x) is simply another way of saying 'y'.
\n" ); document.write( "y = -9x -10
\n" ); document.write( ".
\n" ); document.write( "The slope = m= -9.
\n" ); document.write( ".
\n" ); document.write( "The y-intercept is where x=0, which means y = -10.
\n" ); document.write( ".
\n" ); document.write( "Graphing is a good way to check, but you need to points to draw a line.
\n" ); document.write( "At this point, you have only one point: (0, -10).
\n" ); document.write( ".
\n" ); document.write( "Another good one to find is the x-intercept, which occurs when y=0.
\n" ); document.write( ".
\n" ); document.write( "0 = -9x -10
\n" ); document.write( "9x = -10
\n" ); document.write( "x = -10/9
\n" ); document.write( ".
\n" ); document.write( "So the point is (-10/9, 0)
\n" ); document.write( ".
