For the three-part question that follows, provide your answer to each part in the given work space. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C. The equation of the linear function shown is

.

Linear function with points (0,3) and (2,-1)

Part A: Use the equation to create a table of values using

-x values of -1, 3,

and 5.

.

Remember, the ordered pairs can be verified using the graph.

Part B: Calculate the slope of the line. Show all work.

Part C: Given the graph of a linear function, how can the slope be identified as positive or negative without using the slope formula? Explain.
