The general equation of a straight line is y = m x + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
How to check which of the sets of equations represent the two lines graphed?
We can simply draw a graph using the Desmos graphing calculator and compare it with the given graph of a set of lines.
