What is the distance between (-1,4) and (2,0)

Ivahew [28]

Answer: 5

The Distance between the coordinates of two points is measured by distance formula.

Step-by-step explanation:

The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by

Distance PQ= $\sqrt{}$ (x2-x1)²+(y2-y1)²

So, the distance between (-1,4 ) and (2,0) can be calculated by

Distance= $\sqrt{}$ (2-(-1))²+(0-4)²

= $\sqrt{}$ (3)²+(-4)²

= $\sqrt{}$ 9+16 = $\sqrt{}$ 25 as $\sqrt{}$ 25 = 5

Distance = 5

So the distance between the two coordinates is 5.
