Expanding and simplifying,
y - 4 = 2x - 6
y = 2x - 6 + 4
y = 2x - 2
This is the equation of the line passing through (3,4) with slope 2.

Mastering Point Slope Form: A Comprehensive Practice Worksheet Answer Key
In the realm of algebra, understanding the point-slope form of a linear equation is crucial. It's a fundamental concept that bridges the gap between the abstract and the practical, allowing students to translate real-world scenarios into mathematical models. This article delves into the intricacies of the point-slope form, providing a detailed answer key for practice worksheets to help students and educators alike.
Understanding Point Slope Form
The point-slope form of a linear equation is expressed as y - y1 = m(x - x1), where m represents the slope of the line, and (x1, y1) is a point on the line. This form is particularly useful when you know the slope of a line and a point through which the line passes. It's a versatile tool that can be used to find the equation of a line given various pieces of information.
Components of Point Slope Form
The equation y - y1 = m(x - x1) consists of several key components:
- Slope (m): This is the rate of change of the line, often described as 'rise over run.' It indicates the steepness and direction of the line.
- Point (x1, y1): This is a specific coordinate that lies on the line. It's used to anchor the line in the coordinate plane.
Practice Worksheet Answer Key
Below is a comprehensive answer key for a typical point-slope form practice worksheet. This key provides step-by-step solutions to common problems, helping students understand the process behind each solution.
Problem 1: Find the equation of the line with a slope of 2 passing through the point (3, 4).
Solution:
Using the point-slope form y - y1 = m(x - x1), substitute the given values:
y - 4 = 2(x - 3)
Simplify the equation:
y - 4 = 2x - 6
Add 4 to both sides to solve for y:
y = 2x - 2
Problem 2: Find the equation of the line passing through the points (1, 2) and (3, 4).
Solution:
First, find the slope (m) using the formula m = (y2 - y1) / (x2 - x1):
m = (4 - 2) / (3 - 1) = 2 / 2 = 1
Now, use the point-slope form with one of the points, say (1, 2):
y - 2 = 1(x - 1)
Simplify the equation:
y - 2 = x - 1
Add 2 to both sides to solve for y:
y = x + 1
Common Mistakes to Avoid
When working with point-slope form, students often make the following mistakes:
- Incorrect Slope Calculation: Ensure that the slope is calculated correctly by using the correct formula and points.
- Substitution Errors: Double-check the substitution of values into the point-slope form to avoid simple arithmetic mistakes.
- Simplification Errors: Carefully simplify the equation to avoid errors in the final form.
Conclusion
Mastering the point-slope form is essential for understanding linear equations and their applications. By practicing with worksheets and using the provided answer key, students can enhance their problem-solving skills and gain confidence in their abilities. Remember to take your time, double-check your work, and seek help when needed. With dedication and practice, you'll become proficient in using the point-slope form to solve a variety of problems.
