The best way to solve this problem is to use the point slope formula for the equation. This is y-y1 = m(x-x1). In this formula, "m", is the slope and the x1= -10, y1= 10. You can plug in for m, x1 and y1 in the form above. With that you can rearrange the equation to get it into the form of y=mx+b as well, where b is the y intercept. Good Luck!
