Question

I know the vertical intercept, I think, but I don’t know the slope.

Answer 1

Since the line passes through the origin, the vertical and horizontal intercept is 0.

Now, we can see that the line passes through the points (0,0) and (8,-10).

Therefore, the slope is

$\begin{gathered} m=\frac{8-0}{-10-0} \\ =-\frac{8}{10} \\ =-\frac{4}{5} \end{gathered}$

Hence, the slope is -4/5.
