The equation \(-2x-3=5\) is to be solved graphically.
(i) Write down the equations of the two lines you would graph to solve \(-2x-3=5\).
(ii) Write down the solution of the equation.
Part a:
\(y = 2x - 3\) and \(y = 5\)
\(y = -2x + 3\) and \(y = 5\)
\(y = -2x - 3\) and \(x = 5\)
\(y = -2x - 3\) and \(y = 5\)
Correct
Part b:
\(x=\)
