We find the slope of a line by dividing the vertical change by the horizontal change between two points on the line. We can use the slope formula for this: $m=x_{2}−x_{1}y_{2}−y_{1} .$ Thus, we need to identify two points on the line.

The two points on the line are given as $(0,0)$ and $(-3,5)$. When we substitute them into the formula we get: $m=-3−05−0 =-35 =-35 $ It's a negative slope, because the line is sloping downward. The mistake Ron-Jon made was in calculating the slope. The points did not line up accordingly. The coordinates must be put into the slope formula in the correct order.
