Class 11 Point -slope form

Class 11 Point -slope form- In mathematics, the point-slope form of the equation of a straight line is given by:

y−y1​=m(x−x1​)

where:

• (x1​,y1​) are the coordinates of a point on the line,
• m is the slope of the line.

To understand this formula, let’s break it down:

• (x1​,y1​): These are the coordinates of a point on the line. You can choose any point that lies on the line.
• m: This represents the slope of the line. The slope is the ratio of the vertical change (Δy) to the horizontal change (Δx) between two points on the line. It is often calculated as m=ΔxΔy​.

Using the point-slope form, you can easily write the equation of a line if you know a point on the line and its slope.

Here’s an example:

Suppose you have a point (2,3) that lies on a line, and the slope of the line is m=4. The point-slope form of the equation for this line would be:

y−3=4(x−2)

You can later manipulate this equation into different forms, such as the slope-intercept form (y=mx+b) or the standard form (Ax+By=C), depending on the context or requirements of a specific problem.

What is Class 11 Point -slope form

The point-slope form of the equation of a straight line is a concept typically covered in high school algebra, including in Class 11. The point-slope form is given by:

y−y1​=m(x−x1​)

where:

• (x1​,y1​) are the coordinates of a point on the line.
• m is the slope of the line.

This form is useful for writing the equation of a line when you know a point on the line and its slope. Here’s a brief explanation of the components:

• (x1​,y1​): These are the coordinates of a point on the line. You can choose any point that lies on the line.
• m: This represents the slope of the line, which is the ratio of the vertical change (Δy) to the horizontal change (Δx) between two points on the line. The slope is often calculated as m=ΔxΔy​.

Case Study on Class 11 Point -slope form

Highway Construction Project

Background: Imagine you are a student in a Class 11 mathematics class, and your class is working on a case study related to a highway construction project. The project involves the design and construction of a new section of highway through a hilly terrain.

Problem Statement: The civil engineering team working on the project needs to design a portion of the highway that ascends a hill with a specific slope. Your task is to use the point-slope form to write the equation of the highway segment that passes through a given point on the hill and has the required slope.

Given Information:

1. Point on the Hill: A survey indicates that the highway passes through the point (2,150), where x=2 represents the distance (in kilometers) along the highway and y=150 is the elevation (in meters) at that point.
2. Required Slope: The engineers have determined that the highway should ascend with a slope of 3 meters per kilometer.

Solution Steps:

Step 1: Understand the Point-Slope Form:

• Recall the point-slope form: y−y1​=m(x−x1​), where (x1​,y1​) is a point on the line, and m is the slope.

Step 2: Identify the Given Information:

• (x1​,y1​)=(2,150) is the given point.
• m=3 is the required slope.

Step 3: Plug the Values into the Point-Slope Form:

• Substitute the values into the point-slope form: y−150=3(x−2)

Step 4: Simplify the Equation:

• Distribute the slope 3 to both terms inside the parentheses: y−150=3x−6

Step 5: Finalize the Equation:

• Combine like terms and rearrange if necessary: y=3x−6+150 y=3x+144

Conclusion: The final equation y=3x+144 represents the highway segment through the hilly terrain. It ensures that the slope of the highway at any point along this segment is 33 meters per kilometer, meeting the engineering specifications.

In this case study, the point-slope form proved to be a valuable tool in expressing the mathematical relationship between the elevation of the highway and its distance along the terrain. Students in Class 11 can apply this concept to real-world scenarios, making connections between mathematical principles and practical applications in fields like engineering and construction.
