The variables x and y are connected by the
equation + 2y = 4. Some values of x and
the corresponding values of y are given in the table
(a) Find the value of p and ola,
(b) On a sheet of graph paper, using a scale of
1 em to represent I unit on the x-axis and 2 em
to represent 1 unit on the y-axis, draw the
graph of -x + 2y = 4 for -55x55.
(c) The point (r, 0.5) lies on the graph in (h),
Find the value ofr.
(d) (i) On the same axes in (h), draw the graph
of x = 3
(ii) State the y coordinate of the point on the
graph of -x + 2y=4 that has an x-coordinate
of 3
