solve 9x + 3y = -3 for graphing
Answers
Answer:
Step-by-step explanation:
To represent the solutions of any equations we firstly assume a numeric value for one of them and then solve further the value of another.
Thus,
For x = 1 : 9x + 3y = - 3
9( 1 ) + 3y = - 3
9 + 3y = - 3
3y = - 3 - 9
3y = - 12
y = - 4
Thus for x = 1 | x | 1 |
| y | - 4 |
Thus the point ( 1 , - 4 ) is a solution for the given equation.
For y = 1 : 9x + 3y = - 3
9x + 3( 1 ) = - 3
9x + 3 = - 3
9x = - 6
x = - 2 / 3
Thus for y = 1 | x | - 2 / 3 |
| y | 1 |
Thus point ( - 2 / 3 , 1 ) represents an another solution for this equation.
Henceforth, repeating the same process again and again a definite graph can be prepared.
