Remember that to find the equation of a straight line you need to know its gradient and a point on the line. In some instances you are told the value of the gradient, however there are times where you ...

The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must ...

To become proficient in geometry, students must learn about a variety of lines and angles. One important concept is understanding parallel, perpendicular, and intersecting lines. These lines are basic ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
