Use the graph to write an equation of the line. y= Question 2 Interpret the slope. The cost of the meal increases $0.20 for each dollar spent on the tip. The tip increases $0.20 for each dollar spent on the meal. The cost of the meal increases $0.50 for each dollar spent on the tip. The tip increases $0.50 for each dollar spent on the meal.

The equation of the line is:

The slope is of $0.2, which means that the tip increases $0.20 for each dollar spent on the meal.

The equation of a line, in slope-intercept form, is:

In which:

In this problem:

The equation of the line is:

x is the cost of the meal, y is the tip, thus, the slope is of $0.2 means that the tip increases $0.20 for each dollar spent on the meal.

$0.20

Step-by-step explanation:

Note that the graph does not have a vertical intercept other than (0, $0); it shows a proportional relationship.  For each $1 increase in the cost of the meal, the tip increases by $0.20.
