Question 5

Which statements did you include in your answer?

Revolt · Accepted Answer

The slopes are different.; The y-intercepts are different.

Question 6

✔ intersect at one pointcoincideare parallel

Revolt · Accepted Answer

intersect at one point; Selection 1: intersect at one point; Selection 2: exactly one solution

Question 7

Explain how you can determine that the following system has one unique solution – without actually solving the system.

Revolt · Accepted Answer

Rewrite both equations in slope-intercept form. Their slopes are −2 and −1, so the lines intersect at exactly one point. That intersection is the system’s unique solution.

Question 8

How should you modify the graph to show the solution to the system of inequalities below? Check all that apply. [image 1] [image 2]

Revolt · Accepted Answer

Shade above 2x + y = 4.; Shade below 2y = 6 – 2x.; Make the boundary line 2x + y = 4 dashed.
