how can i plot this piceise function?

>> x = 0 : 0.01 : 25;
for k = 1 : length(x)
if x < 6.7
y(k) = 1200*x;
elseif x >= 6.7 && x < 12
y(k) = 83*x;
else
y(k) = -1200*x;
end
end
plot(x, y);
grid on;

y(k) = 1200*x(k);
elseif x(k) >= 6.7 && x(k) < 12
y(k) = 83*x(k);
else
y(k) = -1200*x(k);
end
end
plot(x, y);
grid on;

i want the funktion to raise when x 0-->6.7 and stay 83 from x 6.7 --> 12 and then drop when above 12
