Question

find the distance between the following pairs of points (i) (-1 ,7) (3 ,-2)

wrong answer will be reported

Answer 1

Let x1 = -1

x2 = 7.

y1 = 3

y2 = -2

by using distance formula we have

√ (x1-x2) ²+(y¹-y2) ²

= √ ( -1-7)²+(3+2)²

=√( -8)²+(5)²

= √ 64+25

= √ 89 cm is the final required answer.
