Question

Now let us draw the graphs of y = –1/3 x, y = – x, y = – 3x by selecting suitable points on these lines.

Let us now draw the graphs of y = 2x – 1, y = 2x + 1, y = 2x + 5, first individually and then on the same axes.

Draw the graphs of the following sets of lines. In each case, reflect on the role of 'a' and 'b'.

Draw the graph of the following equations, and identify their slopes and y-intercepts. Also, find the coordinates of the points where these lines cut the y-axis. Are any of the lines parallel?
