N1=64;
Y1=fft(y,N1);
x= (0:29);
subplot(3,1,2)
plot(x,abs(Y1))
xlabel('Frequency (Hz)');
ylabel('Amplitude');
%HOW TO MAKE IT SAME LENGTH?(LINE5)

The number of elements in ‘Y1’ in the plot need to be the same as the number in ‘x’ so one way would be to re-define ‘x’ to be the desired length with respect to ‘Y1’ and another would be:
plot(x,abs(Y1(1:numel(x))))
Use the approach that gives the desired result.
