Mate, that's true , but aren't all people good at maths nor are all god in drawing...
Yeah, but this is a basics. It's like aren't all people good in drawing, but everybody could draw a circle, square or a line
Well you can't expect a baby to draw a circle or a line.
I'm a baby in this community, I'm only 14.
If you need to draw a line, you should make 2 points and connect them. It's easy. Even if you are 14 years old. Trust me.
