Draw the graph of the lines y = x, y = 2x, y = 3x and y = 5x on the same graph sheet. Is there anything special that you find in these graphs?
उत्तर
(i) y = x
(ii) y = 2x,
(iii) y = 3x
(iv) y = 5x
(i) y = x
When x = 1, y = 1
x = 2, y = 2
x = 3, y = 2
(ii) y = 2x
When x = 1, y = 2
x = 2, y = 4
x = 3, y = 6
(iii) y = 3x
When x = 1, y = 3
x = 2, y = 6
x = 3, y = 9
(iv) y = 5x
When x = 1, y = 5
x = 2, y = 10
x = 3, y = 15
When we plot the above points & join the points to form line, we notice that the lines become progressively steeper. In other words, the slope keeps increasing.
