Use the distance formula to find the distance between (1,3) and (4,-1)

The answer is 5

√ (1-4) ² + (3+1) ²

√ (9+16)

√25=5

That distance is 5 units.

Step-by-step explanation:

There are several very similar forms for the distance formula.

One is d = √[ (x2 - x1) ^2 + (y2 - y1) ^2 ].

x1 and x2 are the two given x values, which in this case are 1 and 4.

Then we have: d = √[ (4 - 1) ^2 + (-1 - 3) ^2 ]

or d = √[ (3) ^2 + (-4) ^2 ]

or d = √ (9 + 16) = 5
