For example, put x = 4 into the equation: y = 13 – (5 x 4). Making y = -7. Do this for the ... Plot the x and y values you have calculated as coordinates on the graph. Draw a line for the ...

In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...
