Title: Pull for Converting between point slope and slope intercept form ticket

Used converting_between_slope_intercept_and_standard_form.html as a template. However, in that exercise there is a problem for converting going both ways. The exercise in the newly added converting_between_point_slope_and_slope_intercept.html only has a problem converting from point slope to slope intercept form since I didn't see a good way to ask the question for going the other way (i.e. slope intercept to point slope form). I suppose I could have provided a given data point on the line as part of the problem. If that would be a better way to go let me know and I can add it, too.
