In the coordinate plane Oxygenthe line passes through the point USA(–2 ; 0) and parallel to the line
d: 2x – y + 2 = 0 has the equation as:
A. 2x – y = 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: 2x – y + 4 = 0
