How would I write and graph an equation with slope -2 and y-intercept (0,0)?
\n" ); document.write( "-------------
\n" ); document.write( "y = mx + b is the slope-intercept equation form of a line.
\n" ); document.write( "Your slope is m = -2
\n" ); document.write( "Your intercept is b = 0
\n" ); document.write( "Your equation is y = -2x
\n" ); document.write( "--------------------------
\n" ); document.write( "Let x=0, then y = 0
\n" ); document.write( "Let x=1, then y = -2
\n" ); document.write( "Let x=2, then y = -4
\n" ); document.write( "__________________
\n" ); document.write( "You have three points: (0,0),(1,-2),(2,-4)
\n" ); document.write( "Plot the points and draw a line thru them to see your graph.
