Transcript text: Point $A$, located at $(-11,-7)$ on the coordinate plane, is reflected over the $x$-axis to form point $B$. Then point $B$ is reflected over the $y$-axis to form point $C$. What are the coordinates of points $B$ and $C$ ?
Point $B$ : $(11,-7)$
Point B: $(-11,7)$
Point $B:(11,-7)$
Point B: $(-11,7)$ Point $C$ : $(-11,7)$ Point $C$ : $(11,-7)$ Point $C$ : $(11,7)$
Point $C$ : $(11,7)$
Solution
Solution Steps
Step 1: Reflect point \( A \) over the \( x \)-axis to find point \( B \)
To reflect a point over the \( x \)-axis, the \( x \)-coordinate remains the same, and the \( y \)-coordinate changes sign.
Given point \( A = (-11, -7) \), the reflection over the \( x \)-axis is:
\[
B = (-11, 7)
\]
Step 2: Reflect point \( B \) over the \( y \)-axis to find point \( C \)
To reflect a point over the \( y \)-axis, the \( y \)-coordinate remains the same, and the \( x \)-coordinate changes sign.
Given point \( B = (-11, 7) \), the reflection over the \( y \)-axis is:
\[
C = (11, 7)
\]
Step 3: Verify the coordinates of points \( B \) and \( C \)
From the calculations:
Point \( B \) is \( (-11, 7) \).
Point \( C \) is \( (11, 7) \).
These match the correct options provided in the question.
Final Answer
Point \( B \) : \((-11, 7)\)
Point \( C \) : \((11, 7)\)
