You just need two points to graph a line.
When x = 1
y - 4 = -1/4(1 - 5)
y - 4 = -1/4(-4)
y - 4 = 4/4
y - 4 = 1
y = 5
So, we have our first point, (1,5)
When x = 2
y - 4 = -1/4(2 - 5)
y - 4 = -1/4(-3)
y - 4 = 3/4
y = 4 3/4
Now we have the point (2, 4 3/4)
Now just run a line through the two points and you're done!
Answer:
512 i dont really know what you are asking for but the smallest number is 512 which also has a small value
S
9x3 matrix has 9 rows and 3 columns, so it has 27 elements
For this case we must resolve the following inequality:

Subtracting 8 from both sides of the inequality:

Equal signs are added and the same sign is placed.

Thus, the solution is given by all values of "y" greater than or equal to -20.
Answer:
"y" belongs to the set [-20,∞)
