Find the distance between each pair of points: a) - 3 , - 7 and 2, 5 c) - a , - b and a , b b) 0, 0 and - 2, 6 d) 2 a , 2 b and 2 c , 2 d

To determine

(a)

To find:

The distance between points -3,-7 and 2, 5.

Explanation

The distance between two points (x1,y1) and (x2,y2) can be determined by,

d=(x2-x1)2+(y2-y1)2

From the given points -3,-7 and 2, 5,

x1=-3

y1=-7

x2=2

y2=5

Substitute these values in the distance formula,

d=(x2-x1)2+(y2-y</

To determine

(b)

To find:

The distance between points 0, 0 and -2, 6.

To determine

(c)

To find:

The distance between points -a,-b and a,b.

To determine

(d)

To find:

The distance between points 2a,2b and 2c,2d.
