Question

What is the distance between the points (4, 7) and (4, –5)?

A. 12 units

B. 4 units

C. 2 units

D. 0 units

Answer 1

\[\huge d = \sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\]

Distance formula

Answer 2

12

Answer 3

\[d=\sqrt{(x_2−x_1)^{2}+(y_2−y_1)^{2}}\]
\[d=\sqrt{(4−4)^{2}+(7−(-5))^{2}}\]
\[d=\sqrt{0+(12)^{2}}\]
\[d=\sqrt{0+144}\]
\[d=12\]
