Draw the graphs of the following equations on the same system of co-ordinates. Write the co-ordinates of their points of intersection.

x + 4 = 0

y - 1 = 0

2x + 3 = 0

3y - 15 = 0

Given equation are

The figure is shown below:

• On a graph paper draw the X-axis and the Y-axis.

• Since it is given that x = -4 and x = -1.5, draw a line on the left of the Y-axis at a distance of 4 and 1.5 units from it and parallel to it.

• Since it is given that y = 1 and y = 5, draw a line above the X-axis at a distance of 1and 5 units from it and parallel to it.

• These lines, parallel to the two axes, are the graphs of the given equations.

• And these lines are intersects at the point A(-1.5,1), B(-4,1),C(-1.5,5) and D(-4,5).
