Answer 1

Answer:

If u see when we joi these points a triangle is forming and we know the measure of base and height . So by applying Pythagoras theorem we can find the distance of . So

By Pythagoras theorem

H²=P²+B²

H²=(4)²+(3)²

H²=16+9

H²=25

H=√25

H=5

So the distance between AB is 5cm

Answer 2

Answer:

a) 5 units is the length of AB .

&

b) –10 or 6 is the abscissa of the other end .

Explanation:

(a) Point A is on the y-axis, it means the value of x = 0.

:. x1 = 0 , y1 = 4

:. x2 = -3 , y2 = 0

By using distance formula, we get

d(A,B) = 5 units

(b) Let's take the abscissa of the other end is 'm'

:. x1 = –2 , y1 = 3

:. x2 = m , y2 = 9

&

:. Distance of line segment is 10 units

By using distance formula, we get

the value of 'm' is –10 or 6

It means the value of abscissa is –10 or 6

Refer the above attachment for getting the distance formula.
