Определи точку графика линейной функции y=5x-4​

Ithink teenagers all over the world have the same problems. as for me, i get along with other students in my class rather well. they don't call me names, they help me if i need any help. i have no problems with my parents, too. i can invite any friends home. what i'm really fed up  with is sharing a room with my younger brother. sometimes i get so angry with him! my parents aren't happy about his marks at school. so i have to take care of him. i'm depressed of doing his homework with him every day. if i don't help him, my parents won't allow me to go out on saturday evening.
