Question
Draw the graph of each of the following linear equations in two variables:
3 = 2x +y
Solution
3 = 2x +y
3 = 2x + y
⇒ y = 3 – 2x
Table of solutions
X |
1 |
0 |
y |
1 |
3 |
We plot the points (0, 3) and (1, 1) on the graph paper and join the same by a ruler to get the line which is the graph of the equation 3 = 2x + y.
