Draw the graph of the equation, y = −x.

Solution

The given equation is y = -x.
Putting x = 0, we get y = 0.
Putting x = 1, we get y = (-1).
Thus, we have the following table:

x 0 1

y 0 -1

On a graph paper, draw the lines X'OX and YOY' as the x-axis and y-axis, respectively.
Now, plot the points A(0,0) and B(1,-1) on the graph paper.
Join AB and extend it on both sides.
Thus, line AB is the required graph of the equation, y = -x.

(1) Draw the graph of y = x² and y = 2x + 3 and hence solve the equation x² − 2x − 3 = 0.

(2) Draw the graph of y = 2x²and y = 3 − x and hence solve the equation 2x² + x − 3 = 0.

(3) Draw the graph of y = 2x² and y = 3 + x and hence solve the equation 2x² − x − 3 = 0.

y = (x + 2) (2 - x)

y = x^{2} + x - 2
