Plotting a Straight Line GraphFrom Supplied Data
Draw the graph of the following data.
x -3 -2 -1 0 1 2 3 4
y -11 -9 -7 -5 -3 -1 1 3
First (-3, -11), then (-2, -9) and so on.

Draw the Axes
These are the two lines at right angles to each other which give us our scale.
First the x-axis and it’s scale. Remember it goes from –3 to +4
x
Draw the axes at right angles to each other.
We have to consider to values of the two variables. Here we have an ‘x’ value that goes from –3 to +4

Now that we have drawn the axes, we can start to think about the plotting of the points.
We have to consider the coordinates in pairs.
The first pairs of coordinates are (-3, -11)
This means we measure 3 units along the x-axis to the left of the 0, since the value has a minus sign, (-3)
And we measure 11 units down the y-axis, again since the value has a minus sign.

Once all the points have been plotted, you should draw the BEST STRAIGHT LINE, which best shows the data so that further work can be done on it.
