Question

9 → the point which lies on y- axis at a distance of 5 units in the negative direction of the y- axis is

10 → if ( x+2,4)=(5,y-2), the coordinates (x ,y) are ​

Answer 1

Answer:

10 - option C (3,6)

Step-by-step explanation:

x+2=5. y-2=4

x=5-2. y=4+2

x= 3. x= 6

Answer 2

Answer:

☆ Hii Friend! ☆

Step-by-step explanation:

☆ Question:

1)The point which lies on y- axis at a distance of 5 units in the negative direction of the y- axis is ?

2)If ( x+2,4)=(5,y-2), the coordinates (x ,y) are ?

☆ Solution:

1)Given the point lie on Y-axis this shows that its x-coordinate is zero.

•Also, it is at a distance of 5 units in negative direction of Y-axis , so its y-coordinate is negative.

•Hence, the required point is (0,-5).

2) ( x+2,4)=(5,y-2)

Comparing both,

(i) x + 2 = 5

=》x = 5 - 2

=》x = 3

(ii) y - 2 = 4

=》y = 4 + 2

=》y = 6

==》Coordinate of x is 3 and y is 6.
