SJoseph_CreatingLinearEquations_111917.docxAssume y = Tom’s Salary amount in dollars
x = the number of years worked
1. Use the data to find the rate of change, or the salary increase per year. ) Hint: Compute the slope
At the beginning (x = 0) Tom’s salary is $75000. After four years (x=4) Tom’s salary is $83000. We have now two points which are (0, 75000) and (4, 83000). We can then compute the slope as follows
The rate of change is equal to the slope. Therefore Tom’s salary is increasing at a rate of $2000 per year.
2. Use the data given and the slope value from step 1 to write the slope-intercept form.
We can use the starting point which is (0, 75000) and the slope = 2000 to solve for the slope intercept of the line. Using point slope form
Therefore the slope intercept form of the line is y = 2000x + 75000
3. Based on your equation on step 2 what till Tom’s salary be in ten years.
In 10 years that means x = 10 and using the line from step 2 tom salary can be anticipated in 10 years as follows
