The gradient of \(y = 3x + 7\) is 3. Any line with a gradient of 3 will be parallel to \(y = 3x + 7\). Two examples are \(y = 3x - 2\) and \(y = 3x + 11.6\). Find the equation of a straight line ...

Parallel rules help draftsmen, surveyors, cartographers, architects, and navigators draw accurate parallel lines. The instrument comes in two main forms: two rectangular straight edges connected by ...

For example, the perpendicular gradient to ... as the gradient of 𝑦 equals 3𝑥 add 4, meaning these two lines are actually parallel. And for 3𝑦 equals 12 subtract 𝑥, dividing by 3 ...
