Find the length of chord AB. Assume the graph is scaled by ones. Give exact and approximate answers. Round to the nearest hundredth.
O sqrt(34); 5.83 units
O sqrt(24): 4.90 units
O sqrt(26): 5.10 units
O sqrt(10): 3.16 units

Choice C

exact length = sqrt(26) units

approximate length = 5.10 units  

=======================================================

Work Shown:

We can use the distance formula.

A = (x1,y1) = (2,2)

B = (x2,y2) = (1,-3)

The distance from A to B is exactly sqrt(26) units which approximates to 5.10 units. This distance represents the length of chord AB.
