I am trying to graph two equations y1 = 25x + 10 and y2= x^2 on the same plot and finding the intersection.

However, i get a error when i type out the second equation. What is strange is that it plots if i change the second equation to something like y2= sin(x). What am i doing wrong?

Also how would I label the axes.

Look at the plot function for labeling the axes.

x=-10:10;%decide on what you want the x-values to be
y1=25*x+10;
y2=x.^2;
plot(x,y1,x,y2);
