In this post, you will learn how to determine the point-slope form of a line given two points or given a point and a slope. You will also see how to graph and how to determine x and y intercepts using point-slope form.
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) 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.
The point-slope form calculator will show you how to find the equation of a line from a point on that line and the line's slope. Soon, you will know what is point-slope form equation, and learn how is it different from the slope-intercept form equation.
This algebra video tutorial provides a basic introduction on how to graph linear equations in point slope form. It contains a few examples and practice prob...
Learn how to write the equation of a line using point-slope form, represent equations in both slope-intercept and standard form, and find the line that passes through a point and is parallel or perpendicular to the graph of a given equation.
The point-slope form is a great tool to find the equation of a line when you know the slope and a point on the line. By understanding how to use the formula and apply it step by step, you can easily graph and write equations for lines.
Basically, the point-slope form of a line is derived from the concept of finding the slope of a line when two points are given. In other words, if you can remember the Slope Formula then the point-slope form should naturally come to you.
Math lesson covering point slope form, complete with graphics and examples. Clearly explains how to plot an equation on a graph and how to format an equation in point slope form.
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in slope-intercept form y=mx+b, to highlight the same line's slope and y-intercept.
To graph an equation in point slope form, the first step is to extract the known point and slope from the equation. The equation is: y−y1=m(x−x1) The slope will be m and the known point will be the coordinate (x1,y1).
