Answer
Given,
⇒ 2x + 3y = 6
⇒ 3y = 6 - 2x
⇒ y =
⇒ y = ………..(1)
When x = 0, = 2 - 0 = 2,
x = 3, y = = 2 - 2 = 0,
x = 6, y = = 2 - 4 = -2.
x | 0 | 3 | 6 |
---|---|---|---|
y | 2 | 0 | -2 |
Steps of construction :
Plot the points (0, 2), (3, 0) and (6, -2) on graph.
Join the points.
Comparing equation (1) with y = mx + c, we get :
m = and c = 2.
Hence the slope of the line = and y intercept = 2.
