5 Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is
equal to 1-2-(-7) units.
Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate
plane is equal to 2 + 9 units.
Is either Laura or Ryan correct? Explain.

Answer:

Ryan is correct.

Step-by-step explanation:

Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is  equal to 1-2-(-7) units.

Here, x-coordinates are same, so the distance between these points is the difference between y-coordinates.

Distance between (4, -2) and (4, -7) = -2-(-7)

                                                           = -2+7

                                                           = 5 units.

So, Laura is incorrect.

Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate  plane is equal to 2 + 9 units.

Here, y-coordinates are same, so the distance between these points is the difference between x-coordinates.

Distance between (2, 3) and (-9,3) = 2-(-9)

                                                         = 2+9

                                                          = 11 units.

Therefore, Ryan is correct.
