Introduction

In mathematics, line transformations are a crucial concept in understanding the behavior of lines and their properties. When a line is transformed, its slope and y-intercept change, resulting in a new line. In this article, we will explore the transformation of Line A ${$ (y = 3x + 1)$}$ into Line B ${$ (y = 2x - 7)$}$ and determine the new slope and y-intercept.

What is a Line Transformation?

A line transformation is a process of changing the slope and y-intercept of a line to obtain a new line. This can be achieved through various methods, including scaling, reflection, and rotation. In this case, we will focus on the transformation of Line A into Line B.

Transformation of Line A into Line B

To transform Line A into Line B, we need to compare the two equations:

Line A: ${$ (y = 3x + 1)$}$ Line B: ${$ (y = 2x - 7)$}$

By comparing the two equations, we can see that the slope of Line A is 3, while the slope of Line B is 2. This indicates that the slope of Line B is flatter than the slope of Line A.

Determining the New Slope

The new slope of Line B can be determined by comparing the coefficients of x in the two equations. In Line A, the coefficient of x is 3, while in Line B, the coefficient of x is 2. Therefore, the new slope of Line B is 2.

Determining the New y-Intercept

The new y-intercept of Line B can be determined by comparing the constant terms in the two equations. In Line A, the constant term is 1, while in Line B, the constant term is -7. Therefore, the new y-intercept of Line B is -7.

Conclusion

In conclusion, the transformation of Line A into Line B results in a new line with a slope of 2 and a y-intercept of -7. The slope of Line B is flatter than the slope of Line A, indicating a change in the steepness of the line.
