Question

The point (-2, -1) satisfies which of the following inequalities?

A) 5x - 2y + 1 > 0
B) -5x + 2y + 1 > 0
C) -2x + 5y - 1 > 0
D) 2x + 5y - 1 > 0

Answer 1

Ik for s fact the awnser not a

Answer 2

Answer:

B) $-5x + 2y + 1 > 0$

Step-by-step explanation:

Given point is (-2,-1)

to find out which inequality satisfies this point we plug in x and y value of the given point in each inequality

A) $5x - 2y + 1 > 0$

x=-2 and y=-1

$5(-2) - 2(-1) + 1 > 0$

$-10+2+1>0$

$-7>0$ is False

B) -5x + 2y + 1 > 0

$-5(-2) +2(-1) + 1 > 0$

$10-2+1>0$

$9>0$ is True

C) -2x + 5y - 1 > 0

$-2(-2) +5(-1) -1 > 0$

$4-5-1>0$

$-2>0$ is False

D) 2x + 5y - 1 > 0

$2(-2) +5(-1) - 1 > 0$

$-4-5-1>0$

$-10>0$ is False
