## Point Slope Form

### Point-slope form is a way to express the equation of a straight line in the form y – y₁ = m(x – x₁), where (x₁, y₁) represents a point on the line and m represents the slope of the line

Point-slope form is a way to express the equation of a straight line in the form y – y₁ = m(x – x₁), where (x₁, y₁) represents a point on the line and m represents the slope of the line.

To understand this form, let’s break down its components:

– (x₁, y₁): These are the coordinates of a point on the line. The x₁ value is the x-coordinate of the point, and the y₁ value is the y-coordinate. These values can be obtained from a given point on the line, or sometimes they will be provided in the problem.

– m: This represents the slope of the line. The slope describes how steeply the line rises or falls. It is a measure of the change in the y-coordinate divided by the change in the x-coordinate. The slope can be calculated using the formula m = (y₂ – y₁)/(x₂ – x₁), where (x₂, y₂) are the coordinates of another point on the line.

The point-slope form is useful for expressing the equation of a line when you know a point on the line and its slope. It gives a clear and concise representation of the line’s equation by stating the coordinates of a point and the slope. This form can be easily converted into other forms like slope-intercept form or standard form to suit different needs in solving mathematical problems.

For example, if we are given a point (2,4) on a line with a slope of 3, the point-slope form of the equation for this line would be:

y – 4 = 3(x – 2)

This equation can be simplified or rearranged into other forms, depending on the required form or further steps in solving the problem.
