Introduction to Point-Slope Form<\/p>\n
Point-slope form is a linear equation that represents a line on the coordinate plane. It is expressed as:<\/p>\n
y – y\u2081 = m(x – x\u2081)<\/p>\n
where (x\u2081, y\u2081) is a point on the line and m is the line\u2019s slope. This form is particularly useful when you know a point and the slope of a line, as it simplifies calculating and representing the line\u2019s equation.<\/p>\n
Definition of Point-Slope Form<\/p>\n
Point-slope form is a linear equation that describes the relationship between the coordinates of a point on a line and the line\u2019s slope. It is defined as:<\/p>\n
y – y\u2081 = m(x – x\u2081)<\/p>\n
where:<\/p>\n
– y represents the y-coordinate of any point on the line.<\/p>\n
– y\u2081 represents the y-coordinate of a given point on the line.<\/p>\n
– m represents the slope of the line.<\/p>\n
– x represents the x-coordinate of any point on the line.<\/p>\n
– x\u2081 represents the x-coordinate of a given point on the line.<\/p>\n
Applications of Point-Slope Form<\/p>\n
Point-slope form has various applications in mathematics and related fields. Some common uses include:<\/p>\n
1. Finding the equation of a line when given a point and its slope.<\/p>\n

Step-by-Step Procedures for Point-Slope Form<\/p>\n
To use point-slope form, follow these step-by-step procedures:<\/p>\n
1. Identify the given point (x\u2081, y\u2081) and the line\u2019s slope (m).<\/p>\n
2. Substitute the values of x\u2081, y\u2081, and m into the point-slope form equation.<\/p>\n
3. Simplify the equation to obtain the final line equation in point-slope form.<\/p>\n
Example 1<\/p>\n
Given the point (2, 5) and a slope of 3, find the line\u2019s equation in point-slope form.<\/p>\n
Step 1: Identify the given point and slope.<\/p>\n
– Point: (2, 5)<\/p>\n
– Slope: 3<\/p>\n
Step 2: Substitute the values into the point-slope form equation.<\/p>\n
y – 5 = 3(x – 2)<\/p>\n
Step 3: Simplify the equation.<\/p>\n
y – 5 = 3x – 6<\/p>\n
y = 3x – 1<\/p>\n
The equation of the line in point-slope form is y = 3x – 1.<\/p>\n
Example 2<\/p>\n
Given the point (4, -3) and a slope of -2, find the line\u2019s equation in point-slope form.<\/p>\n
Step 1: Identify the given point and slope.<\/p>\n
– Point: (4, -3)<\/p>\n
– Slope: -2<\/p>\n
Step 2: Substitute the values into the point-slope form equation.<\/p>\n
y – (-3) = -2(x – 4)<\/p>\n
Step 3: Simplify the equation.<\/p>\n
y + 3 = -2x + 8<\/p>\n
y = -2x + 5<\/p>\n
The equation of the line in point-slope form is y = -2x + 5.<\/p>\n
