Which of the following is the correct graph of the inequality $$y

A graph with a dashed line for $$y = 2x - 1$$ and shading below the line.

A graph with a solid line for $$y = 2x - 1$$ and shading above the line.

A graph with a dashed line for $$y = 2x - 1$$ and shading above the line.

A graph with a solid line for $$y = 2x - 1$$ and shading below the line.

Graph the inequality $$x + y > 2$$ on Desmos. Which of the following is true about the graph?

The line $$x + y = 2$$ is dashed, with shading above the line.

The line $$x + y = 2$$ is solid, with shading below the line.

The line $$x + y = 2$$ is dashed, with shading below the line.

The line $$x + y = 2$$ is solid, with shading above the line.

Using Desmos, which feature allows you to see the exact coordinates of the intersection point of two lines?

The "Points of Interest" feature

What is the solution to the system of inequalities $$y \geq -x + 1$$ and $$y

The region above the line $$y = -x + 1$$ and below the line $$y = 2x - 3$$ .

The region below the line $$y = -x + 1$$ and above the line $$y = 2x - 3$$ .

The region above both lines $$y = -x + 1$$ and $$y = 2x - 3$$ .

There is no solution to this system of inequalities.

If you are using Desmos to graph the equation $$y = \frac{1}{3}x + 2$$ , which of the following steps is unnecessary?

Checking the graph for symmetry.

Entering the equation into the expression list.

Setting up sliders for the slope and y-intercept.
