Draw the graph of the equation 3x + 2y = 6. Find the coordinates of the point, where the graph cuts the y-axis.
The given equation is 3x + 2y = 6
2y = 6 - 3x
∴ y =
Now, if x = 2, then
y = = 0
And, if x = 4, then
y = = -3
Thus, we have the following table:
x | 2 | 4 |
y | 0 | -3 |
Plot points (2, 0) and (4,-3) on a graph paper and join them to get the required graph.
We find that the line 3x + 2y = 6 cuts the y-axis at a point P which is 3 units above the x-axis.
So, co-ordinates of P are (0,3).
