Question

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.

Answer 1

Answer:

$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.

Answer 2

The equation of the line is:

$y = 0.2x$

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:

$y = mx + b$

In which:

• m is the slope, which is how much y changes when x changes by 1.
• b is the y-intercept, which is the value of y when x = 0.

In this problem:

• When x = 0, y = 0, thus the y-intercept is $b = 0$.

• When x = 10, y = 2, thus, considering that the slope is given by change in y divided by change in x:

$m = \frac{2 - 0}{10 - 0} = 0.2$

The equation of the line is:

$y = 0.2x$

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.
