You can put this solution on YOUR website! The y-intercept is the point where the graph crosses the y-axis. This is the point where x= 0. When the equation is given in this form, if you let x=0, then the y-intercept is just the constant term, which is -7.
When the equation is written in this form, it turns out that the slope is the coefficient of x, which in this cse is 3/5. The slope means the rise over the run, or vertical distance over the horizontal distance.
These two items make graphing the line very easy. Start by graphing the y intercept, by going down on the y-axis 7 units, and put a point.
Next, with your pencil on that y-intercept, move up a rise of 3, then move from that point right 5 units and put the second point. Connect the two points, and you have your graph. It should look like this:
