Here are the basic steps on how to do it. <em>4-7x=18</em> Now you move the 4 onto the other side of the equal bars. <em>4-4-7x=18-4</em> Do the total. <em>-7x=14</em> Now you divide 14 by -7. <em>x=-2</em> There you have it. <u><em /></u><em>Hope this helps!</em>
The rate of change would be 7. you would plot your first point on the graph at (-2,0) and the next one would be up 7 and over 1 for your next plot point.
