Equation 2
X 3 4 5 6 7 8

Y 2 6 10 14 18 22

Solving a simultaneous equation
The intersecting point of the two lines gives the values of
x and y.x = 3 and y = 2.
Points to be remembered when plotting
• Indicate the name or symbol of the quantity plotted along each axis, with its unit.
• Indicate clearly the scale division on each axis.
• Choose a convenient scale.
• Mark clearly the points plotted.
• Draw the axes lines thicker than the plotted and joined line/curve for distinguishing.
