for the system of inequalities y >= 2x  1 and y <= 3x  1, which of the following statements best descibes the ordered pair (1,1)
a)The point (1,1) is a solution for y >= 2x  1, but not y <= 3x  1.
b) The point (1,1) is not a solution for either equation.
c)The point (1,1) is a solution for the entire system.
d)The point (1,1) is a solution for y <= 3x  1, but not for y >= 2x  1
d

Did you test the point ???
for (1,1)
first equation: 1 ≥ 21 , or 1 ≥ 1, true
2nd equation: 1 ≤ 31 , or 1 ≤ 2, true
mmmhhh?
