Question

Equation of the line passing through (1, 2) and parallel to the line $y = 3 x - 1$is.

• A. $y + 2 = x + 1$
• B. $y + 2 = 3 ( x + 1 )$
• C. $y - 2 = 3 ( x - 1 )$
• D. $y - 2 = x - 1$

Answer 1

Answer: (C)

$y - 2 = 3 ( x - 1 )$

Answer 2

The required equation which passes through (1, 2) and its gradient is $m = 3$ , is $( y - 2 ) = 3 ( x - 1 )$ .
