Q: How would the equation where x=3 and y=4 be represented in a XY graph, and what does it say about the relationship between X and Y?
- There is a straight horizontal line on the X-axis beginning at the point x=3. A straight vertical line starts along the Y-axis originating at y=4. The relationship indicates that the value of X is not dependent on the value of Y.
- The beginning point y=4 on the Y-axis has horizontal line to the right from that point, X also has a horizontal straight line from x=3. The lines for x and y will not cross but run in parallel with each other.
- The beginning point y=4 on the Y axis has a horizontal line straight to the right, X-axis has a vertical line straight up from x=3. With the two points on the graph, there is an intersection point where the x and y will cross each other.

Q: How would the equation x=0 and y=5 be represented in a XY graph, and what does it say about the relationship between X and Y?
- The beginning point y=5 on the Y-axis has a horizontal line to the right, X-axis has a vertical line straight up from x=0. There is an intersection point where the x and y will cross each other further to the right of x=0.
- A straight line along the horizontal axis begins at the point x=0. A vertical line along the Y axis originating at y=5. It indicates that the value of X and the value of Y are always 5.
- A single point y=5 on the Y-axis has a horizontal line to the right from that point. This graph indicates that y is not dependent upon x.
A: A single point y=5 on the Y-axis has a horizontal line to the right from that point. This graph indicates that y is not dependent upon x.

Q: In this time series graph, the unemployment rate fluctuates from around 4% to 10%. Given this information, if 2017 had an unemployment rate of around 4-5%, was 2017 a year where it was easier or harder to find employment than 1986 and why?
- It was easier to find work in the late 1980s than in 2017 because the unemployment rate was lower than 2017.
- Finding work was much easier in 2017 because of access to the internet and a higher unemployment rate than in 1986.
- It was more difficult to find work in 1986 because the unemployment rate was close to 6% and thus an economy worse off than the economy of 2017.
A: It was more difficult to find work in 1986 because the unemployment rate was close to 6% and thus an economy worse off than the economy of 2017.

Q: In this time series graph, the unemployment rate fluctuates from around 4% to 10%. Given this information, 1987 had an unemployment rate of around 6%. Look at the year 2015 and compare whether it was easier or harder to find employment with 1986 and why?
- It was easier to find work in the late 1980s than in 2015 because the unemployment rate was lower than 2015.
- It was more difficult to find work in 1986 because the unemployment rate was close to 6% and thus an economy worse off than the economy of 2015.
- Finding work was equally as effortful in 2015 as it was in 1986 because both of those years had economic conditions where unemployment was around 6%.
A: Finding work was equally as effortful in 2015 as it was in 1986 because both of those years had economic conditions where unemployment was around 6%.
