Question 1

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

Accepted Answer

$$(2, 1)$$

Question 2

Based on the second image, what is the domain of the relation shown?

Accepted Answer

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

Question 3

Based on the second image, what is the range of the relation shown?

Accepted Answer

$$\{2, 1, 3, 5\}$$

Question 4

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

Accepted Answer

$$-\frac{5}{2}$$

Question 5

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

Accepted Answer

The system is independent.

Question 6

If the equation of the blue line in the first image is $$y = 2x - 3$$, what is the equation of the red line?

Accepted Answer

$$y = -12x + 2$$

Question 7

Given the points $$(-4, 3)$$, $$(-2, 1)$$, $$(3, 2)$$, and $$(4, 5)$$ from the second image, does this relation represent a function?

Accepted Answer

Yes, because each $$x-$$value is paired with exactly one $$y-$$value.
