Karate is my favorite sport
My favourite sport is karate, which is one of the Oriental martial arts. Karate is a popular sport in the world because it improves self-confidence and self-discipline, memory and attention. Besides, karate teaches us self-defence, respect, self-control and patience.
I started practising karate when I was eight. Since that time I have been training twice a week in our local sports centre. The lessons are physically hard but I enjoy them. Our sensei teaches us patiently and inspires us to become better people. I have already participated in a few competitions.
I am glad that I chose karate because it gives me so much: I have become more patient and physically stronger.

y = -3x+1.5
3x = 1.5-y
x = 0.5 - y/3
Подставлять необходимые значения y
x1 = 0.5 - (-4.5)/3 = 0.5 + 1.5 = 2 [2;-4.5]
x2 = 0.5 - (0)/3 = 0.5 [0.5;0]
x3 = 0.5-(1.5)/3 = 0.5-0.5 = 0 [0;1.5]
