Which of the following options best describes the slope of line a?

the slope of line A would be 3/4.

Step-by-step explanation:

The slope of line a would be 3/4. find a point on the line and find the next point that intersects on the graph. the distance up and over from those points is your slope

Tamara's example is in fact an example that represents a linear functional relationship.

This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached). The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
