# How do you label points where the line crosses the axes?

I am doing homework and this is the equation: y= -x -4 along with graph to chart it on. We are working on integer linear equations and graphing on charts. If you could help, it would clear some things up for me! Thanks, Clara

Hi Clara,

You are asking how to label the points where the line crosses the axis, is that correct?

Like Andy answered you, your slope is -1, (or -1/1, rise over run) and your y-intercept is -4 (since y = mx + b).

Since you know that you have a point at (0,-4), you can then use your slope, -1, to find another point on your line for this equation. From the point (0,-4), you would move down one unit ( -1 "rise") and to the right 1 unit (positive 1 "run"), placing your next point at (1,-5). You mark both of these points with a very small circle or "dot" and connect the lines with a ruler, putting an arrow on each end since it goes on forever.
