Before plotting a graph, make sure that the equation has a single `y` on one side of the equals sign, and the `x` values are all on the other side. If the graph to be plotted is given as a function (`f(x)`), then it has already been correctly arranged.
Plot the graph as instructed in the question. For linear graphs, use a straight edge. For other graphs, draw a clear line keeping curves as regular as possible and passing through all the points.
If a sketch has been requested, show on the sketch the coordinates for the intercept with the `y`-axis, the roots of the equation (crossing the `x`-axis) and any turning points. A ruler must be used for the sketch - for the axis and any linear function.
Sketch the graph for `y=2x+3`. Show the coordinates of the intercept points on the `x`-axis and the `y`-axis.
Complete the table as indicated. Solve the equation for `y=2x+3` for the intercept on the `x`-axis.
2(-6) + 3 = -9
2(0) = 3 = 3
2(3) + 3 = 9
Complete the following table for the equation `4x^2=y + 6x - 2`
Rearrange the equation `y+6x-2=4x^2`
And substitute for the two missing values
