Question

will give 50 points!!
What is the length of the line segment PQ on the coordinate grid?

A four-quadrant coordinate grid from negative 50 to positive 50 in increments of 10 is drawn. Point P is plotted on the ordered pair negative 20, 30. Point Q is plotted on the ordered pair 30, 30. The points are connected by a line.

10 units
20 units
30 units
50 units

Answer 1

Answer:

50 units

Step-by-step explanation:

The y-coordinate of both points is 30.  Therefore, the line connecting the points is horizontal.  To calculate the length of the line segment PQ, simply subtract the x-coordinate of point P from the x-coordinate of point Q:

30 - -20 = 3 + 20 = 50
