Question

The distance between A(1,0) and B(-1,2)

Answer 1

Answer:

2√2 units

Step-by-step explanation:

Given there are two points in coordinate plane such that,

• A = (1,0)
• B = (-1,2)

To find the distance between them.

We know that,

Distance between two points (a,b) and (c,d) is given by,

• $\sqrt{ {(a - c)}^{2} + {(b - d)}^{2} }$

Here, we have,

• a = 1
• b = 0
• c = -1
• d = 2

Substituting the values,

Therefore, we will get,

$= > d = \sqrt{ {(1 + 1)}^{2} + {(0 - 2)}^{2} } \\ \\ = > d = \sqrt{ {(2)}^{2} + {( - 2)}^{2} } \\ \\ = > d = \sqrt{4 + 4} \\ \\ = > d = \sqrt{8} \\ \\ = >d = 2 \sqrt{2}$

Hence, required distance between the points is 2√2 units.

Answer 2

Answer:

0,2

Step-by-step explanation:

$\sqrt{(x1 - x2}) + \sqrt{(y1 - y2)}$

A(1,0)

B(-1,2)

by applying the above formula :

=√{1+1}+{0-2}

= √2-2

= 0

if my answer cames wrong just change the sings of formula . thanks
