No, yes, yes
(-28,-11) and (8.7)
}[/tex]
Step-by-step explanation:
Given that a line in two dimension is parametrized by

a) If t is non negative, then (-28,-11) cannot lie on that part
(-28,-11) No because t =-5
(8,7) yes because t =1
(26,16) yes because t = 4
b) when t lies between -2 and 1
we have left end point as

(-10,-2) is left end point
Right end point is when t =1 i.e.
(8,7)
c) when the points should be above x axis, y should be non negative
i.e. 
So t should lie in the interval
