You can put this solution on YOUR website!
All of the possible solutions are written in \"y=mx%2Bb\" format, where:
\n" ); document.write( "m = slope
\n" ); document.write( "b = Y-intercept
\n" ); document.write( ".
\n" ); document.write( "You are given the information that the slope is 4 and that the line goes through a point. If you graph the point (-1,-3), you can figure out the Y-intercept. Simply count 4 units \"up\" on the graph (positive direction) and 1 unit to the \"left\" on the graph (also positive direction). Why? because the slope is the change in y divided by the change in x. So on the graph, you are now sitting at point (0,1). Thus 1 is the Y-intercept.
\n" ); document.write( ".
\n" ); document.write( "So the correct equation of the line is:
\n" ); document.write( "\"highlight%28y=4x%2B1%29\"
\n" ); document.write( ".
\n" ); document.write( "==============
