Question:
while solving linear eq. with variables in graphical method we can apply any number eg.(0,8) (4,4)
Answer:
Use the solutions to Graph the Equation.
Substitute x = 0 in the equation and find a value for y that makes the resulting equation true.
For example, in the equation x - 2y = 2, when x = 0, the equation becomes -2y = 2
Since y = -1 makes this equation true, one point on the line is (0,-1)
So, in this way we can apply any number.
