A line passing through the point (12, –5) has a slope of One-third. Complete the work shown:

1. Substitute known values for m, x1, and y1:

2. Distribute the slope through the parentheses:

3. Distribute the slope through the parentheses:

4. Solve for the y-variable:

y minus (negative 5) = one-third (x minus 12). Y + 5 = one-third (x minus 12). Y + 5 = one-third x minus 4.

y = one-third x
