Question

Nick and his cousin Sara have the same birthday but Nick is four year older that’s Sara. Let the variable x represent nicks age and y represent Sara’s age which graph represents the relationship between nicks and Sara’s age

Answer 1

To represent the relationship between Nick's and Sara's age, we can use a scatter plot with age on the x-axis and y-axis.

One possible graph may look like this:
- The x-axis represents Nick's age (variable x), ranging from 0 to some maximum value.
- The y-axis represents Sara's age (variable y), also ranging from 0 to the same maximum value.

Since Nick is four years older than Sara, the data points on the graph would fall along a straight line, roughly parallel to the y-axis and passing through the point (4, 0). This line represents the relationship: for every point on the line, the x-coordinate (Nick's age) is four units greater than the y-coordinate (Sara's age).

If we have additional information about the specific ages of Nick and Sara, we can plot the exact data points on the graph to create a more accurate representation.
