Equation of a Straight Line - Math is Fun
https://www.mathsisfun.com/equation_of_line.html
Web ResultEquation of a Straight Line. The 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 you find "m" and "b"?

Web ResultMay 19, 2023 · If line L passes through the point (x1,y1) ( x 1, y 1) and has slope m, then the equation of the line is. y −y1 = m(x −x1) (3.4.5) (3.4.5) y − y 1 = m ( x − x 1) This form of the equation of a line is called the point-slope form. To use the point-slope form of a line, follow these steps.

Web ResultThere are three main forms of linear equations. Example. A line passes through the points ( − 2, − 4) and ( − 5, 5) . Find the equation of the line in all three forms listed above. Two of the forms require slope, so let's find that first. slope = m = Δ y Δ x = 5 − ( − 4) − 5 − ( − 2) = 9 − 3 = − 3.

Web ResultPoint-Slope Equation of a Line. The "point-slope" form of the equation of a straight line is: y − y 1 = m (x − x 1) The equation is useful when we know: one point on the line: (x1, y1) and the slope of the line: m, and want to find other points on the line. Have a play with it (move the point, try different slopes): Now let's discover …
