Introduction
In mathematics, the x-intercept of a line is the point at which the line crosses the x-axis. It is a crucial concept in algebra and geometry, and understanding how to find the x-intercept of a line is essential for solving various mathematical problems. In this article, we will explore the concept of x-intercept and apply it to two different lines, Line A and Line B. We will find the x-intercept of each line and compare their values.
Line A: Finding the x-Intercept
The equation of Line A is given by:
To find the x-intercept of Line A, we need to set y = 0 and solve for x.
Step 1: Set y = 0
Step 2: Simplify the equation
Step 3: Divide both sides by 2
Step 4: Subtract 3 from both sides
Therefore, the x-intercept of Line A is -2.
Line B: Finding the x-Intercept
The values of Line B are given in the table below:
| x | y |
|---|---|
| -6 | 0 |
| -3 | -4 |
To find the x-intercept of Line B, we need to find the value of x when y = 0.
Step 1: Identify the value of x when y = 0
From the table, we can see that when y = 0, x = -6.
Therefore, the x-intercept of Line B is -6.
Comparing the x-Intercepts
Now that we have found the x-intercepts of both lines, let's compare their values.
| Line | x-Intercept |
|---|---|
| Line A | -2 |
| Line B | -6 |
As we can see, the x-intercept of Line B is -6, which is greater than the x-intercept of Line A, which is -2.
Conclusion
In this article, we have explored the concept of x-intercept and applied it to two different lines, Line A and Line B. We have found the x-intercept of each line and compared their values. The x-intercept of Line A is -2, while the x-intercept of Line B is -6. This comparison highlights the importance of understanding the x-intercept of a line in mathematics.
