Draw the graph for the linear equation given below :

y = -x + 4

y = -x + 4

Step 1:

Give at least three suitable values to the variable x and find the corresponding values of y.

Let x = -1, then y = -(-1) + 4 ⇒ y = 5

Let x = 0, then y = 0 + 4 ⇒ y = 4

Let x = 1, then y = -1 + 4 ⇒ y = 3

Step 2:

Make a table i(as given below) for the different pairs of the values of x and y:

Step 3:

Plot the points, from the table, on a graph paper and then draw a straight line passing through the points plotted on the graph.
