8-81.

Find the equation of the line through the points $(6, −8)$ and $(0,0)$.

1. What is the slope of the line?

2. Is the point $(3, −4)$ on the line? How can you tell?

Graph the points and make a slope triangle to find the slope.

Substitute the coordinates into the equation to see if the point is on the line.
