Draw the graph of each of the following linear equations and answer the following question.
(i) $y = x$

(ii) $y = 2 x$

(iii) $y = - 2 x$

(iv) $y = 3 x$

(v) $y = - 3 x$
Are all these graphs passing through the origin?

x + y = 4

x - y = 2

y = 3 x

3 = 2 x + y

(i) x + y = 4 (i i) x - y = 2 (i i i) y = 3 x (i v) 3 = 2 x + y

3 x + 2 y - 8 = 0

3 x + 2 y + 12 = 0
