The shortest distance is along the perpendicular to 2x + y + 3 = 0 and through (-21, -1).
1) determine the slope of the perpendicular to 2x + y + 3 = 0
2) determine the equation of the line passing through (-2, -1) having the slope from 2
3) determine the intersection of the two lines
4) use the distance formula using the point of intersection and (-2, -1)
