Объ

у=кх+в.

M1 (1;1) 1=к1+в.

M2(3;4) 4=к3+в. Вычтем из второго первое почленно.

3=к2 . Значит к=1,5

При к=1,5 имеем 1=1,5*1+в, в=-0,5.

Тогда у=1,5х-0,5

ПЕРЕВОД

We need friends everywhere!

Make new friends, but keep the old,

One is silver, the other is gold.

Circle round that has no end

That’s how long I want to be your friend.

A Friend

A friend is like a flower, a rose to be exact,

Or maybe like a brand new gate

That never comes unlatched.

A friend is like an owl, both beautiful and wise

Or perhaps the friend is like a ghost

Whose spirit never dies.

A friend is like a heart that goes strong until the end.

Where would be in this world

If we didn’t have a friend.

you

Your heart is like a treasure,

A source of wealth to keep,

Impossible to measure

Unfathomably deep.

Your love is like the ocean

That reaches deep inside,

My heart sweet with emotion

And I can’t stem the tide.

I’ll love your dear, I’ll love you

Till China and Africa meet

And rivers jump over the mountain

And the salmon sings in the street

I’ll love you till the ocean

Is folded and hung up to dry

And the seven stars go squawking

Like geese about the sky.Friends

Friends care, friends share,
