Is the y intercept a reasonable part of the model explain ?

The defending attorney Mr. Justin Case was interested in how a lengthy trial could affect howlong a jury would deliberate on a case (and see if he should just cut to the chase). He observed asample of courtroom trials and noticed the following:Days inTrial (X) 5 2 6 4 5 6 2 4 2 1  HoursDeliberation (Y) 4 4 1 3 1 3 9 2 3 7 2) What is the Y-intercept?

Now find a single equation that is perpendicular to all of these lines (do not use the y-axis). Can you graph your equation using the calculator? Mocels Lab Exercise 4 Recycling Over time, according to records kept by the Environmental Protection Agency (found at www.epa.gov), recycling rates have increased from 10% of municipal solid waste generated in 1980 to 16% in 1990, to 29% in 2000, and to 34% in 2009. Meanwhile, disposal of waste to a landfill has decreased from 89% of the amount generated in 1980 to 54.3% of solid waste in 2009. The prediction equation (or least- squares prediction equation) for the percent of solid waste recycled by Americans is y = 0.932x -1837 where y = percent of solid waste recycled and x is the year. (a) Graph these data (percent recycled vs. year), leaving room at both ends for past and future years. Draw the line given by the prediction equation on your graph also. (b) Is the slope positive or negative? What does the slope tell us about the rate of…

Consider the equation C space equals space 0.01 m space plus space 35, where C is the cost in dollars of a cell phone plan for month and m is the number of minutes used in one month. Explain the meaning of the slope and of the y-intercept in this equation.
