Question

Draw the graph of the equation 3x + y - 12 = 0. Check
whether the point (3,3) lies on the line represented by the
given equation.​

Answer 1

Step-by-step explanation:

(3,3) means x= 3 and y=3

now to substitute the value of x and y in equation

3x + y - 12 = 0

3(3) + 3 - 12 = 0

9 + 3 - 12 = 0

12 - 12 = 0

0 = 0

So therefore the point (3,3) lies on the line represented by the given equation.
