Like this?
x = 2:0.01:16;
y1 = 15*x + 270;
y2 = (6.6964e-04)*x.^4 - (2.6786e-02)*x.^3 + (9.0625e-01)*x.^2 - (1.2768e+01)*x + 2.7211e+02;
y3 = (4.6503e-03)*x.^5 - (2.4368e-01)*x.^4 + (4.7656e+00)*x.^3 - (4.1525e+01)*x.^2 + (1.6586e+02)*x + 2.0000e+02;
plot(x, y1, 'linewidth', 1.5)
hold on
plot(x, y2, 'linewidth', 1.5)
plot(x, y3, 'linewidth', 1.5)
hold off
grid on
xlabel('Freq')
ylabel('Spectral')

Modify the code for y1 only:
x1a = 2:0.01:8;
x1b = 8:0.01:10;
x1c = 10:0.01:16;
y1a = 15*x1a + 270;
y1b = 15*x1b + 270;
y1c = 15*x1c + 270;
plot(x1a, y1a, 'b-', 'linewidth', 1.5)
hold on
plot(x1b, y1b, 'b--', 'linewidth', 1.5)
plot(x1c, y1c, 'b-', 'linewidth', 1.5)

x = [......]; % use values of observations
y1 = [.....]; % use values of observations or form expression
y2 = [.....]; % use values of observations or form expression
y3 = [.....]; % use values of observations or form expression
figure(1);
plot(x, y1, x, y2, x, y3);
xlabel('Frequency Slots --->');
ylabel('Spectral Efficiency');
legend('Average User rate','Fair Spectrum Sharing','No Spectrum Sharing');
