#1
Start with the given distance formula
where )
is the first point )
and )
is the second point )
Plug in , , ,
Evaluate to get -2. Evaluate to get -1.
Square each value
Add
So the distance approximates to
which rounds to
2.2
So the distance between (1,1) and (3,2) is approximately 2.2 units
#2
Start with the given distance formula
where is the first point )
and is the second point )
Plug in , , ,
Evaluate to get -2. Evaluate to get -3.
Square each value
Add
So the distance approximates to
which rounds to
3.6
So the distance between (4,0) and (6,3) is approximately 3.6 units
#3
Start with the given distance formula
where is the first point )
and is the second point )
Plug in , , ,
Evaluate to get 0. Evaluate to get 4.
Square each value
Add
Simplify the square root (note: If you need help with simplifying the square root, check out this solver)
So the distance between (5,2) and (5,-2) is 4 units
#4
Start with the given distance formula
where is the first point )
and is the second point )
Plug in , , ,
Evaluate to get 0. Evaluate to get -2.
Square each value
Add
Simplify the square root (note: If you need help with simplifying the square root, check out this solver)
So the distance between (1,3) and (1,5) is 2 units

Find the distance between the two points given.Round to the nearest tenth,if necessary,(1,1)and(3,2).
-----------------------------
Formula: d = sqrt[(1-3)^2 + (1-2)^2)] = sqrt[4 + 1] = sqrt(5)
================================
The next one is,Find the distance between the two points given.Round to the nearest tenth,if necessary,(4,0)and(6,3).
--------------------------------
d = sqrt[(4-6)^2 + (0-3)^2] = sqrt[4+9] = sqrt(13)
===========================
The third one is Find the distance between the two points given.Round to the nearest tenth,if necessary,(5,2)and(5,-2).
---------------------------
Follows the same pattern.
=======================
And the last one is,Find the distance between the two points given.Round to the nearest tenth,if necessary,(1,3)and(1,5).
------------------
Follows the same pattern.
========================
Cheers,
Stan H.
