Linear Relations Review

#1. Estimating values beyond the known data for a relation is extrapolation interpolation a line of best fit discarding outliers #2. This table shows the population of Canada from 1861 to 2001. a) Make a scatter plot of the data.b) Draw a line of best fit. #3. Use your graph from question 2 to describe thea)trendb) relationshipc) correlation. #4. A new restaurant is having advertising flyers printed. The cost to design and layout the flyer is $500. There is an additional cost of $0.15 per flyer printed.a) Identify the fixed cost (initial value) and the variable cost (rate of change) of this partial variation.b) Write an equation representing this relationshipc) Use your equation to determine the total cost of 500 flyers. #5. Which of the following statements about the tables shown is true? Tables (a) and (b) are both linear. The rate of change in table (a) is 4. The rate of change in table (b) is -8 Tables (a) and (b) both represent partial variations. #6. The price charged to repair a computer is $60, plus $50 Write an equation representing this relationshipb) What is the total cost of a repair that takes 3.5 h?c) If you were charged $135, how many hours did it take to repair your computer? #7. Which statement is false? The rate of change of a linear relation is also referred to as slope. Rate of change can be calculated as rise Non-linear relations have constant first differences. In the equation y=mx+b, the rate of change is represented by "m" and the initial value is represented by "b". #8. This graph shows the cost of producing 1000 copies of a school yearbook as it relates to the number of pages in the yearbook.a) Calculate the rate of change. How does it relate to the graph?b) Write an equation for this relationship.c) Describe how the equation and graph would change if the base cost changedto $9000.
