Question

Select the correct answer.

Which test point holds true for y-2x ≤ 1?
A. (0,2)
B. (-2,4)
C. (1,4)
D. (5,0)

Answer 1

Explanation:

y - 2x < = 1

basically, all u have to do is sub in ur test points into ur inequality to see if it is true

y - 2x < = 1.......(0,2)

2 - 2(0) < = 1

2 - 0 < = 1

2 < = 1.......not true

y - 2x < = 1....(-2,4)

4 - 2(-2) < = 1

4 + 4 < = 1

8 < = 1......not true

y - 2x < = 1......(1,4)

4 - 2(1) < = 1

4 - 2 < = 1

2 < = 1......not true

y - 2x < = 1....(5,0)

0 - 2(5) < = 1

-10 < = 1 .......this one IS TRUE

ur answer is D
