Question

On the coordinate plane below, Point P is located at (2,-3), and point Q is located at (-4,4).

Find the distance between points P and Q Round your answer to the nearest whole number.

Answer 1

9

Explanation:

We can use the distance formula

d = sqrt ( ( y2-y1)^2 + ( x2-x1) ^2)

d = sqrt ( ( 4- -3)^2 + ( -4 -2) ^2)

= sqrt ( ( 7^2 + ( -6)^2)

= sqrt( 49+ 36)

= sqrt(85)

9.219544457

Rounding to the nearest whole number

= 9
