Divide both sides by 2 to give 𝑦 = 3𝑥 + 5. It is now clear that the two lines both have a gradient of 3 so are therefore parallel. Find the equation of the line parallel to 𝑦 = 4𝑥 + 3 ...

Lines which are parallel have the same gradient. For example, \(\text{y = 2x + 1}\) and \(\text{y = 2x - 2}\) will be parallel because they both have a gradient of 2. We want to determine if the ...

Amid the ideas and wordplay, the author’s new novel only occasionally recalls the brilliance of his Patrick Melrose quintet ...
