Equation of a Straight Line - Math is Fun
https://www.mathsisfun.com/equation_of_line.html
WEBThe equation of a straight line is usually written this way: y = mx + b. (or "y = mx + c" in the UK see below) What does it stand for? y = how far up. x = how far along. m = Slope or Gradient (how steep the line is) b = value of y when x=0. How do we find "m" and "b"? b is easy: just see where the line crosses the Y axis.

Equation of Line - Formula, Find | What is Equation of Line?
https://www.cuemath.com/geometry/equation-of-a-line/
WEBThe equation of a line is linear in two variables, usually x and y, that is satisfied by points of the line. The equation of line is usually found by the point-slope form y - y_1 = m (x - x_1), where m is the slope and (x_1, y_1) is a point on the line.
