Answer:
a) The first image is the plot of the set S. The plot correspond only to the four points.
b) The set is not convex because the points that lies in the segment between (1,5) and (5,1) doesn't belong to the set.
The set can be convexifies adding the linear combinations of the points of S.
The graph of smallest convexification of the set is in the second image that correspond to the polygon with vertices (1,5),(5,1),(4,4),(0,0).
The translation of the question given is
A line that passes through the points A (2,1) and B (6,3) and another line passes through A and through the point (0, y). What is y worth, if both lines are perpendicular?
Answer:
y = 5
Step-by-step explanation:
Line 1 that passes through A (2,1) and B (6,3)
Slope (m1) = 3-1/6-2 = 2/4 = 1/2
y - 1 = ( x -2)
2y - 2 = x- 2
y =
Line 2 passes through A (2,1) and (0,y)
slope (m2) =
Line 1 and Line 2 are perpendicular
m1*m2 = -1
*
= -1
y-1 = 4
y = 5
slope = -2
Equation of Line 2
Y-1 = -2(x-2)
y -1 = -2x +4
2x +y = 5
