Question

Which ordered pairs are solutions to the inequality y – 2x ≤ –3

Choose all answers that are correct.
A-(-6, -3)
B-(0, -2)
C-(1, -1)
D-(5, -3)
E-(7, 12)

Answer 1

put values of x and y in the equation

Answer 2

Plug them in.

(-6, -3)

y - 2x ≤ –3

-3 - 2(-6) ≤ –3

-3 - -12 ≤ –3

9 ≤ –3

Option A is incorrect.

(0, -2)

y - 2x ≤ –3

-2 - 2(0) ≤ –3

-2 - 0 ≤ –3

-2 ≤ –3

Option B is incorrect.

(1, -1)

y - 2x ≤ –3

-1 - 2(1) ≤ –3

-1 - 2 ≤ –3

-3 ≤ –3

Option C is correct.

(5, -3)

y - 2x ≤ –3

-3 - 2(5) ≤ –3

-3 - 10 ≤ –3

-13 ≤ –3

Option D is correct.

(7, 12)

y - 2x ≤ –3

12 - 2(7) ≤ –3

12 - 14 ≤ –3

-2 ≤ –3

Option E is incorrect.
