How can i plot the response of this system? 𝑦[𝑛] = −𝑦[𝑛 − 1] + 5𝑥[𝑛] + 2𝑥[𝑛 − 3]. From an input 𝑥[𝑛] = [5, 1, 2, 3, 1, 0, 1, 2, −1, ]

Ran in:
% 𝑦[𝑛] = −𝑦[𝑛 − 1] + 5𝑥[𝑛] + 2𝑥[𝑛 − 3].
b = [5 0 0 2]; % 5x(n), 2x(n-3)
a = [1 1]; % y(n) + y(n-1)
% From an input 𝑥[𝑛] = [5, 1, 2, 3, 1, 0, 1, 2, −1, ]
x = [5, 1, 2, 3, 1, 0, 1, 2, -1];
y = filter(b, a, x);
stem(y)
