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)
Brilliant_brown [7]

Answer:

(2,0)

Step-by-step explanation:

The solution of the inequality y>-3x+2 is shown in attached diagram.

The boundary line is dotted line, because the sign of inequality is without notion "or equal to". The dotted line means that points lying on this line are not solutions of the inequality. The solutions are those points lying in the shaded region.

From the points (0,2), (2,0), (1,-2), (-2,1) only point (2,0) lies on the shaded region, so only point (2,0) is a solution to the inequality

Veronika [31]

Y=0.213x-352  will represent this linear model shown in the data table.

<h3>What will be the linear model for the given data?</h3>

Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option

So if we put the value x=1980 in the Y=0.213x-352  then

Y=0.213(1980)-352

Y=69.74

These values are closest to 70.1 whereas other options do not satisfy the condition.

Thus Y=0.213x-352  will represent this linear model shown in the data table.
