I think since I'm using a for loop for this it only shows the final point for both graphs, how do I make it show all the points?
if path == 1
for x1 = 0:.2:5
y1 = (x1*2)+2
plot (x1,y1,'c-->')
end
elseif path == 2
for x2 = 0:.2:5
y2 = x2^2
plot (x2,y2,'m:>')
end
end
end

Use hold . You don't need for-loops.
figure
axes
hold on
path =1;
if path == 1
x1 = 0 : 0.2 : 5;
y1 = (x1.*2)+2;
plot (x1,y1,'c-->')
elseif path == 2
x2 = 0 : .2 : 5;
y2 = x2.^2;
plot (x2,y2,'m:>')
end
