Answer:
yes
Step-by-step explanation:
The graph is of a function (one output for every input) that also passes the horizontal line test (one input for every output). Hence it is one-to-one.
For a <em>function</em>, the key for it being one-to-one is that it pass the horizontal line test.
Answer:
$3.50 per mile
Step-by-step explanation:
Slope-intercept form of a linear equation:
(where m is the slope and b is the y-intercept)
Given linear equation:
(where x is the number of miles traveled and y is the total cost)
The rate of change is the slope of the linear equation.
Therefore, the rate of change is $3.50 per mile.
