Refraining part of the function on the graph, while keeping the interval

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.
