Interpret the slope for the situation: the number of people who worked for the railroads in the united states each year from 1989 to 1995 can be modeled by the equation y = -6.61x + 229, where x represents the number of years since 1989 and y represents the number of railroad employees (in thousands).

-6.61

Step-by-step explanation:

Unless there is more included in this problem then -6.61 is the slope. Slope is represented as m in y=mx+b. Simply substituting in the slop and y-intercept shows that m=-6.61 or the slope is -6.61.

A line with a positive slope (m > 0), as the line above, rises from left to right whereas a line with a negative slope (m < 0) falls from left to right.

Step-by-step explanation: If two lines have the same slope the lines are said to be parallel. You can express a linear function using the slope intercept form.
