Question 1

Which of the following best describes the solution to the system of equations represented by the two lines in the first image?

Accepted Answer

The system has exactly one solution because the lines intersect at a single point.

Question 2

Based on the points plotted in the second image, what is the domain of the relation?

Accepted Answer

$$\{-4, -2, 3, 4\}$$

Question 3

What is the range of the relation shown in the second image?

Accepted Answer

$$\{4, 1, 2, 3\}$$

Question 4

What is the slope of the line shown in the third image?

Accepted Answer

$$-3$$

Question 5

Which of the following statements is true about the line in the third image?

Accepted Answer

The line has a negative slope and passes through the y-axis above the origin.

Question 6

If the two lines in the first image represent the equations $$y = 0.5x + 2 ($$blue) and $$y = -x - 1 ($$red), what are the coordinates of their intersection point?

Accepted Answer

Question 7

Which of the following best describes the relation shown in the second image?

Accepted Answer

It is a function because each $$x-$$value is paired with exactly one $$y-$$value.

Question 8

Given the line in the third image, what is the $$y-$$intercept?

Accepted Answer

$$(0, 5)$$

Question 9

If the line in the third image is represented by the equation $$y = -3x + 5$$, what is the $$x-$$intercept?

Accepted Answer

$$(\frac{5}{3}, 0)$$

Question 10

Which of the following best describes the trend of the blue line in the first image?

Accepted Answer

It has a positive slope and increases as $$x$$ increases.
