A road sign says there is an 60% incline. Explain what this means.

The slope of a line is:  2.00 By how much does the Y-variable change if the X-variable decreases by 1 unit?

Graphing -- Order and Coefficient (x, y) 1000 (0.16, 103.12) (0.28, 33.67) 800 (0.36, 20.37) (0.56, 8.42) 600 (0.68, 5.71) (0.84, 3.74) 400 Consider the graph and the selected data pairs given above. Assume the dependency of y on x conforms to 200 y = kxx" On paper, or in a spreadsheet (MS Excel), draw a graph of y versus x" for that choice of the integer n which will produce a straight line. 0.0 0.2 0.4 0.6 0.8 1.0 For this data, what is the exact value of the integer n?

The straight line depreciation for a motorcycle is y = -2,150x + 17,200 A. What is the original price? B. How much value does the motorcycle lose per year? C. How many years will it take for the motorcycle to totally depreciate?

is this slope positive or negative? y=-2x

Ellie earned a total of $10 for 2 hours of yard work. How many hours in all will it take Ellie to earn $20? Assume the relationship is directly proportional.

A person 6 feet tall is walking away from a lamp post at the rate of 47 feet per minute. When the person is 8 feet from the lamp post, his shadow (see dashed line) is 10 feet long. Find the rate at which the length of the shadow is increasing when he is 24 feet from the lamp post. The length of the shadow is increasing at a rate of 6 ft feet per minute.

What is the slope of a road that rises 6 feet for every horizontal change of 100 feet? 50 100 50 3

Assume the world catch of fish in 1950 was 13 million tons and in 1995 it was 98 million tons. Find the average rate of change in the marine catch from 1950 to 1995.

Ms. Dawson’s call did a science experiment. The class started out with 635 bacteria cells. The growth rate predicted was 5.15%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 23 h from the start of the experiment. Be sure to show your work on how you obtained your second value. Round to the nearest whole number.
