Question

Write the co-ordinates y = 22 - 3 line the Questions of the point intersects the y axis​

Answer 1

Answer:

Solved

Step-by-step explanation:

Let the co-ordiantes of P be (x,y) and Q be (x2,y2)

midpoint of PQ=(2,−5)

By midpoint formula,

x=2x1+x2 and y=2y1+y2

2=2x1+x2 and −5=2y1+y2

∴x1+x2=4 and y1+y2=−10

Answer 2

Step-by-step explanation:

Let the co-ordiantes of P be (x,y) and Q be (x

midpoint of PQ=(2,−5)

By midpoint formula,

x=

∴x

=−10

Since line PQ intersects the y-axis at P

So, x

1

=0.

Similarly, y

2

=0

∴x

=4 and y

=−10

The co-ordinates of P are (0,−10) and Q are (4,0).
