ASSIGNMENT
Linear Plot
1. Decide whether each expression is positive or negative without using your calculator. Then check your
answer with your calculator.
a. -35 (44) + 23
b.) -14) (-36) -32
c. 50 – 23 ( -12)
2. List the terms of each number sequence of y- coordinates for the points shown on each graph. Then write
a recursive routine to generate each sequence.
a.
b.
c.
d.
3. Make a table listing the coordinates of the points plotted in a, b, c , d.
a.
b.
c.
d.
4. The direct variation y = 2.5x describes the relationship between two standard units of measurement
where y represents centimeters and x represents inches.
a. Write a recursive routine that would produce a table of values for any whole number of inches. Use a
calculator list.
b. Use your routine to complete the missing values in this table.

a. Graph the data from both tables on the same set of coordinate axes.
b. Describe what you found by graphing the data. How are the graphs the same? How are they different?
c. Does it make sense to draw a line through each set of points? Explain what these lines mean.
d. What is the real-world meaning of the point ( 30, 4) for the USS Alabama?
