Question

Solve the following systems of equations graphically:

x − 2y = 6
3x − 6y = 0

Answer 1

The given equations are:

Putting in equation we get:

Putting in equationwe get:

Use the following table to draw the graph.

Plotting the two points equation (i) can be drawn.

Graph of the equation….

Putting in equation, we get:

Putting x=2 in equationwe get:

Use the following table to draw the graph.

Draw the graph by plotting the two points from table.

We see that the two lines are parallel, so they won’t intersect

Hence there is no solution
