The slope of the line passing through points (-6, 3) and (-6, 39) is

Your answer is undefined.

When we look at your points, we can see that the x value is the same. This means that the line will maintain the same x value, therefore being a vertical line.

The equation of slope is rise/run. When we look at the vertical line, we see that there is no run, as it does not move on the x axis. Therefore, to be calculating the slope, you would be dividing by 0, which makes the equation undefined.

Hope this helped!

The answer is (A large majority of African Americans were slaves.)
