Question:
Equation of a plane parallel to the plane \( 9x - 8y + 7z = 10 \) is:
Equation of a plane parallel to the plane \( 9x - 8y + 7z = 10 \) is:
Show Hint
For parallel planes, the normal vectors are the same, but the constant term varies. Simply adjust the constant term while keeping the direction ratios the same.

- \( 9x - 8y - 7z = 5 \)
- \( 9x - 8y + 7z = 5 \)
- \( 9x + 8y + 7z = 5 \)
- \( 9x - y + 7z = 5 \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The equation of a plane parallel to another plane is obtained by keeping the same direction ratios for the normal vector, but changing the constant. Here, the normal vector of the given plane is \( (9, -8, 7) \). For a plane parallel to this one, we keep the same direction ratios but change the constant to get \( 9x - 8y + 7z = 5 \).

- The monsoon is a seasonal wind pattern that brings significant rainfall to various regions, particularly in Asia and Africa. It typically occurs between June and September and is driven by temperature differences between land and ocean. The warm landmass causes moist air from the ocean to flow inland, resulting in heavy rains. Monsoons are vital for agriculture. They replenish water sources supporting crops like rice and tea. However, they can also lead to severe flooding and landslides, disrupting livelihood and infrastructure. Climate change has led to unpredictable monsoon patterns, causing either excessive rainfall or drought.
