The slope equation is rise over run. Let's use 2 different points to figure it out. (0,5)(1,-4) So you want to do -4-5 divided by 1-0. The outcome will be -9 over 1. So the answer for slope would be -9. For the y-intercept, you want to find the point on the line where it passes through the y-axis. You would write, (0,5) You wrote 0 for x because it is on the y-axis. I hope this helps!
