This is known as the \(y\)-intercept and is represented by the letter \(c\) in \(y = mx + c\). Gradient is a measure of steepness. As you move along a line from left to right, you might go up ...

Any equation that can be rearranged into the form \(y = mx + c\), will have a straight line graph. \(m\) is the gradient, or steepness of the graph, and \(c\) is the \(y\)-intercept, or where the ...
