Question

Draw the graphs of the following straight −lines:

(i) y = 3 − x; (ii) y = x − 3; (iii) y = 3x − 2; (iv) y = 5 − 3x;

(v) 4y = − x + 3; (vi) 3y = 4x + 1; (vii) x = 4; (viii) 3y = 1.

Answer 1

(i) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(ii) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(iii) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(iv) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph sheet.

Upon joining these points, we get the required graph of the straight line.

(v) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(vi) To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(vii) To graph the straight line, we first take different values of y and tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.

(viii)To draw the graph of the straight line, we first take different values of x to obtain their corresponding values of y and then tabulate them as follows:

Now, we locate the points on the graph.

Upon joining these points, we get the required graph of the straight line.
