To show that two lines are parallel, they must have the same gradient ... Solve the equation to find the value of 𝑐. The 𝑦-intercept, 𝑐, is –2. Write the equation of the perpendicular ...

This is known as the \(y\)-intercept and is represented by the letter \(c\) in \(y = mx + c\). As you move along a line from left to right, you might go up, you might go down or you might not ...

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 ...
