Lines that are parallel have the same gradient. 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 ...

Lines that are parallel have the same gradient. 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 ...

If you understand the definition of a mathematical function, a good way to judge it is that any line drawn parallel to the y ... marking points or lines, the graph is spread across the XY-axis.
