Question

For the lines 5x + 2y = 8 and 5x - 2y = 7, which of the following statement is true?

Options

• Lines are parallel

• Lines are coincident

• Lines are intersecting

• Lines are perpendicular

Answer 1

Lines are intersecting.

Explanation:

Let L₁ ≡ 5x + 2y - 8 = 0 and

L₂ ≡ 5x - 2y - 7 = 0, so that m₁ = `-5/2`, m₂ = `5/2`

Lines are neither patallel nor perpe.ndictilar, also not coincident. Hence, the lines are intersecting.
