Unit step and Ramp together

Hello guys I want help .. I try to draw this signals in the pic attached , but the problem is, When i want to draw the ramp function, it starts on X-axis , but it should start from y=2 as the picture shown .. i attached my code too , any suggestions

Here's the code

What does (2 minus ramp) look like?

Maybe the ramps will continue to -infinity ?

Consider:

sympref('HeavisideAtOrigin', 1)

ans = 

syms t
u = @(t) heaviside(t)

u = function_handle with value:
    @(t)heaviside(t)

r = @(t) t

r = function_handle with value:
    @(t)t

f = (u(t-0)-u(t-1.5)) * (2-r(t))

f = 

fplot(f, [-1 5] ); ylim([-1/2 2.5])

This is not exactly what you need: notice that at 1.5 it still has value 1/2. The plain ramp function has slope 1, and if you look at your graph, you need something with slope (0-2)/(1.5-0) = -4/3. I will leave it to you to figure out how you might get a slope of -4/3 for a ramp.
