Question

The coordinate grid shows three points P, Q, and R:

The distance between Q and R is ______ units.

Answer 1

distance between Q and R only relies on x-values. So, here we do not need to use the distance formula.
R (6,-4) = (X1, Y1)
Q (-8,-4)= (X2,Y2)
distance= X1-X2
d= (6-(-8)) = (6+8)= 14 units
