Tell whether the given order pairs are solutions of the inequality.

y ≥ - 2x + 4 ; (0,4) (-1,8)

Answer 1

both

Explanation:

hi! let's plug in the ordered pairs into the equation. the x-coordinate is substituted for x in the equation, while the y-coordinate is substituted for y.

y≥-2x+4

(0,4)

4≥-2(0)+4

4≥0+4

4≥4

this is correct since 4 is equal to 4.

(-1,8)

8≥-2(-1)+4

8≥2+4

8≥6

this is also correct since 6 is less than 8.

therefore, both ordered pairs are solutions of the inequality.
