In the coordinate plane Oxygenthe line passes through the point USA(–2 ; 0) and parallel to the line

d: 2xy + 2 = 0 has the equation as:

A. 2xy = 0 B. 2x y + 4 = 0 C. 2x + y + 4 = 0 D. x + 2y + 2 = 0

Solution method – See details

Step 1: Find the VTPT of (which is the VTPT of d)

Step 2: Write PT of the line passing through USA and have VTPT found in step 1

Detailed explanation

d whose VTPT is \(\overrightarrow n = (2; – 1)\)

Because \(\Delta //d\) ∆ takes \(\overrightarrow n = (2; – 1)\) as VTPT \( \Rightarrow \Delta \) has PT: 2xy + 4 = 0
