I dropped out of school to early I guess, but I bet you guys can help me here. I've got a sloped line starting from point a(0|130) and ending at b(700|0).
I need an equation to calculate the y-coordinate when the point x is given, e.g. 300. Can someone help me please ? Sorry for asking such a dumb question, can't find any answer here, propably just too silly to get the math slang ;)
