Draw the graphs of linear equations y = x and y = – x on the same Cartesian plane. What do you observe?
The given linear equations are:
y = x ------- (i)
Following are some values x and y which satisfy the equation
y = -x ------- (ii)
Following are some values x and y which satisfy the equation (ii)
Plotting the above values in the same graph:
From the above graph it can be observed that the two lines y = x and y = – x intersect each other at (0, 0).
