10.
(a) The equations of 5 lines are given below.
Which one represents a line that is parallel to \(3x + y + 4 = 0\)?
Circle your answer. [1]
Which one represents a line that is parallel to \(3x + y + 4 = 0\)?
Circle your answer. [1]
\(3x - y - 4 = 0\) \(y = 3x - 4\)
\(y = 3x + 4\) \(y = 4 - 3x\) \(x + 3y + 4 = 0\)
(b) A straight line has a gradient of 2 and passes through the point (0, 4).
Find the equation of this straight line.
Give your answer in the form \(y = mx + c\). [2]
