chapter name coordinate geometry class 9 maths​

Answer 1

Answer:

Q2

Answer is 5

Step-by-step explanation:

Q2

since on y axis x=0

if we draw a perpendicular line from (5,7) to y axis

it meets at (0,7)

by using distance formula

$\sqrt{(x2 - x1) { }^{2} + (y2 - y1) {}^{2} }$

distance between two points

or simply we can say that the distance is 5

Q3

if point lies on y axis the x will be zero

so the point is (0,-3)
