Question

What is the distance between 78,2 and 78,103 along the y-axis on a coordinate grid?

Answer 1

The distance is 101.

The only coordinate that changes is the y-coordinate; it goes from 2 to 103:
103-2=101

Answer 2

The points are (78,2) and (78,103) .

Now we have to find the distance between these two points

So we can use the distance formula

So let's use the distance formula between these two points

$d= \sqrt{(x_2 - x_1 )^2 + ( y_2 - y_1)^2}$

$d= \sqrt{(78 - 78 )^2 + ( 103 - 2)^2}$

$d= \sqrt{(0 + 101^2}= \sqrt{101}$

d= 10.05

So distance is 10.05 units
