Q1
If the line 5x - 2y + 10 = 0 is reflected about the x-axis, what is the new equation?
5x + 2y + 10 = 0
5x - 2y - 10 = 0
5x + 2y - 10 = 0
5x - 2y + 10 = 0
Show Solution
Copy
Reflecting about the x-axis changes the sign of y-coefficient: 5x + 2y + 10 = 0.

Q
Q: If the line 5x - 2y + 10 = 0 is reflected about the x-axis, what is the new equation?
Solution:
Reflecting about the x-axis changes the sign of y-coefficient: 5x + 2y + 10 = 0.
Steps: 5
Show Steps
Step 1: Start with the original equation of the line: 5x - 2y + 10 = 0.
Step 2: Identify the coefficient of y in the equation, which is -2.
Step 3: To reflect the line about the x-axis, we need to change the sign of the y-coefficient. So, -2 becomes +2.
Step 4: Rewrite the equation with the new y-coefficient: 5x + 2y + 10 = 0.
Step 5: This is the new equation after reflecting about the x-axis.
