Why is my plot taking so long to plot?

I am trying to plot some stats for a hw assignment. It has a large number of points so I understand it will take a while to load but when I run even a simple plot it takes more than 3 minutes to load. what might be the reason?

Post the code and we will evaluate it.

figure

t = linspace(-5,4,50);

y= -2.* t.^2 + 8.*t +17;

plot(t,y)

title("Position Over Time")

xlabel("Time (sec)")

ylabel("position (ft)")

axis([0, max(t), 0, max(y)*1.1])
