Ответ: y=-5x-15

Объяснение:

Уравнение прямой в Декартовой форме y=kx+b

k=Δy/Δx =(-25-(-10))/(2-(-1))=(-15)/3=-5

Найдем b, подставив координаты одной из точек ( все равно какой)

-25=-5*2+b => b =-15

y=-5x-15

Kira wrote about her family. Read the text and answer the questions.

I think my parents are really good-looking. Mum has an oval face, when she smiles, small wrinkles appear around her eyes. She never uses make-up, and I like it. She has brown eyes and dark eyebrows. My mum's hair is straight and light brown. She usually curls them or wears a low ponytail. If my mum gets angry, a deep line appears on her forehead. I love it when mum smiles, it means everything is fine. My father is quite tall. He is a lot taller than my mum. He is slightly overweight. My mum is always telling him to eat healthy but he really likes sweets. Dad has wavy fair hair and blue eyes. He also wears glasses and has a short beard. Mum says he is really handsome. It's hard to say if I resemble my mum or dad. I have my mum's colouring (dark eyes, brown hair), I have my dad's eyes, mouth and nose, so I think I look a bit more like him. My sister is the opposite- she has my mum's face shape, small nose, bigger forehead and my dad's colouring lighter skin, fair hair. She also wears glasses. So, my sis and I don't really look alike, but you can tell we're sisters when we're with our parents.

1. Who doesn't have straight hair?
2. Who has an oval face?
3. Who has blue eyes?
4. Who has a small nose?
5. Who resembles dad more?
6. Who has got a high forehead?
7. Who isn't fit enough?
8. Who has darker skin?
9. Who wears glasses?​
