I'm new in Matlab, and I'm not sure if you can do this in Matlab.
So, I obtained two solutions to a physics problem, of the simple form:
y=-x-95.07 and
y=10/7*x+18.67
which have an intersection. Now, due to an extra physical condition, only the
part on the left side of the interaction make physicial sense, so, I would like to
create a plot that doesn't show the right side of the interaction, so basicly I want the
lines to appear up to a point, while the interval on the x-axis goes beyond that point!

Try this:
y1 = @(x) -x-95.07;
y2 = @(x) 10/7*x+18.67;
xint = fzero(@(x)y1(x)-y2(x), 1); % Intersection
x = linspace(xint-10, xint);
figure
plot(x, y1(x), x, y2(x))
grid
xlim([xint-10 xint+10])
producing:

Experiment to get the result you want.
