  • False

MCQ
True or False

Solution

This statement is True.

Explanation:

First let’s convert the given equation to intercept form i.e. `x/a + y/b + z/c` = 1

Where, a, b and c are x, y and z intercepts respectively!

Given, 2x – 3y + 5z + 4 = 0

⇒ – 2x + 3y – 5z = 4

Dividing by 4 both side

⇒ `X/(-2) + Y/(4/3) + Z/(4/(-5))` = 1

On comparing, we have intercepts as `-2, 4/3, -4/5`
