Because Manuel chooses to have 16 dinners out per month and the vertical axis of the graph shows
the quantity of dinners out per month, you should have placed the orange point at a vertical
coordinate of 16.
13. Points and slopes
The following graph contains four lines (A, B, C and D), each of which has a slope that is either positive,
negative, zero, or infinite.
For each of the following scenarios, indicate whether the relationship between the two variables is
positive or negative, as well as which line on the previous graph has a slope that reflects this type of
: The X-axis and Y-axis on the graph
labeled intentionally. You need to substitute the
variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-
axis should be labeled “ The average grade received" and Y-axis should be labeled "The number of
hours spent studying".
As the number of hours spent studying rises, the average grade
As the number of hours spent studying falls, the likelihood of
getting an A falls.
As the number of hours spent watching TV rises, the average
grade received falls.
