The coordinate pair can be obtained from the given equation by
rearranging the equation to make <em>y</em> the subject of the equation
- The table of values obtained from the given equation is presented as follows;
- The graph showing the points in the above table is attached
Reason:
The given equation is presented as follows;
2·x - 4·y = 12
(a) The values are found by making either <em>x</em>, or <em>y</em> the subject of the
formula, and inputting values as follows;
2·x - 4·y = 12
= 4·y
4·y = 2·x - 12
The rearranged equation is therefore
Plugging in values of <em>x</em>, (0, 1, 2, 3) to find the corresponding y-values gives;
x = 0
- x = 1
- x = 2
x = 3
x = 4
<u>The table of values</u> is therefore;
The <u>graph of the points</u> can be <u>plotted</u> using MS Excel as presented here
