Which set of coordinates is a solution of the equation 2x - y =11
Just substitute any number for one variable to find the value of the other.
Eg:
2x-y=11
2(1)-y=11
2-y=11
-2 -2
-y=9
-y/-1=9/-1
y=-9
So (1,-9) is a solution to the equation.
Follow the steps and find many more solutions.

The set of coordinates that are solutions of the given equation is required.
All the points on the line \(2x-y=11\) will be a solution of the equation, some of them are \((0,-11),(5.5,0)\)
The given equation is
\(2x-y=11\)
The values of x and y when substituted in the about equation result in the number 11.
So,
\(x=0\)
\(2\times 0-y=11\\\Rightarrow y=-11\)
\((0,-11)\)
\(y=0\)
\(2x-0=11\\\Rightarrow x=\dfrac{11}{2}=5.5\)
\((5.5,0)\)
All the points on the line \(2x-y=11\) will be a solution of the equation.
