The value where the line crosses the \(y\)-axis is 1 Write the equation ... For example, if the steepest incline allowed for a house extension is 15° (this is a gradient of approximately 0Û° ...
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 that is perpendicular to \(y = 2x + 1\).
