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 ...

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 ...

Graphic statics basics. Two forces with parallel lines of action; two concurrent forces; system of concurrent forces; theorem of three forces; funicular polygon; examples (precepts). 2) Static ...

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 ...
