Question

Which ordered pair is a solution of the inequality?
y=> 4x-5

A. (3,4)
B.(2,1)
C.(3,0)
D.(1,1)

Answer 1

each pair is (x,y)

to test if a pair "works"
replace x and y in the equation with the numbers in the pair
for example

for A (3,4) x is 3 and y is 4. use these numbers in
y ≥ 4*x-5
4 ≥ 4*3 -5
now do the arithmetic and see if the statement is true.
in this case, the right side is 4*3-5 = 12-5= 7
4 ≥ 7 is NOT true. So option A is out.

can you test the other choices ?
