That's not a straight line; it's a parabola.
A straight line is y= m*x +c, where m and c are constants.

Hi! Would really appreciate any help :) basically I need to plot a
graph from an equation of a line. I havent got any data, just the
equation. y=x squared+3 The graph should range from x=-4 to x=+4

Thank you :)
