Fig. 11
The graph of y = 3x + 3 is shown in Fig 11 which is a straight line.
(i) Point of intersection of the line with x-axis is – (1, 0)
Point of intersection of the line with y-axis is (0, 3)
(ii)
x – intercept is „-1‟ (It is the intercept of the line on the x – axis)
y-intercept is „3‟ You can also find it directly as c = 3)
(iii)
From the graph, we see that (–2, –3) lies on the line and (3, -2) does not lie on
the line.
You can also check the above facts by directly substituting the values of x and y in the
equation it self.
