How To Write Point Slope Form
Y y 1 m x x 1.
How to write point slope form. Point slope equation of a line point slope equation of a line the point slope form of the equation of a straight line is. Y y 1 m x x 1 where m is the slope of the line x 1 y 1 is a point on the line and x y is any other point on the line. In this case it denotes a specific y value which you will plug into the equation. Y y1 m x x1 y y 1 m x x 1 it should be noted that y1 y 1 does not mean y multiplied by 1. The standard point slope formula looks like this.
To write an equation in point slope form given a graph of that equation first determine the slope by picking two points. You have all the information you need to draw a single line on the map. Recall that if we have two points then we are able to find the slope of the two points by using the slope formula. Point slope form is y y1 m x x1 where x1 and y1 are the coordinates of a point on the line and m is the slope of the line. The letter m in the point slope form equation is a number that represents the slope of the line.
It does not matter which point you pick as long as it is on the line different points yield different constants but the resulting equations will describe the same line. M frac rise run frac y 2 y 1 x 2 x 1 m run rise. Point slope form is a way to write linear equations given by the equation. Notice that point slope form is more or less a rearranged form of the slope formula.
