Question

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 2), and (1, negative 1). Everything to the right of the line is shaded. The solutions to the inequality y > −3x + 2 are shaded on the graph. Which point is a solution? (0, 2) (2, 0) (1, −2) (−2, 1)

Answer 1

Answer:

(2,0)

Step-by-step explanation:

Answer 2

Answer:

(2,0)

Step-by-step explanation:

we know that

If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality

we have

$y > -3x+2$

Substitute the value of  x and the value of y of each point in the inequality and then compare the results

case a) (0, 2)

$2 > -3(0)+2$

$2 > 2$ ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality

case b) (2,0)

$0 > -3(2)+2$

$0 > -4$ ----> is true

so

the point satisfy the inequality

therefore

The point is a solution of the inequality

case c) (1, -2)

$-2 > -3(1)+2$

$-2 > -1$ ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality

case d) (-2, 1)

$1 > -3(-2)+2$

$1 > 8$ ----> is not true

so

the point not satisfy the inequality

therefore

The point is not a solution of the inequality
