Answer:
D
Explanation:
since the x- coordinates of both points are 7 then the points lie on a vertical line.
the distance is then the absolute value of the difference of the y- coordinates, that is
distance = | - 22 - 12 | = | - 34 | = | 34 | = 34 units
or
distance = | 12 - (- 22) | = | 12 + 22 | = | 34 | = 34 units
