EXAMPLE 1: Kelly is 6 years old and is practicing throwing a ball outside of her house. She lives on a slope and is throwing the ball up from a height of 1.75 feet (the height of her outstretched arm) so that she can catch
it when it eventually rolls back to her since she is playing alone. Yeah, she is a smart 6 year old! The slope she
lives on can be represented by: y = { x and the equation of the throwing ball is modeled by: y = -x +3.5x + 1
1) Use technology to graph the two functions and sketch them below, color code and label both equations
with the correct graph (write equations below):
1
2) Identify the solution(s) of the system that
work within the context of this problem.

The minimum wage in washington has been increasing over the last ten years. years 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 washington state minimum wage $6.50 $6.72 $6.90 $7.01 $7.16 $7.35 $7.63 $7.93 $8.07 $8.55 $8.55 a) find the linear regression equation for the minimum wage in washington using this data ( x  0 in 2000). round to the thousandths. b) what is the slope? specifically, what does the slope represent in the real world context? c) what is the y-intercept? specifically, what does the y-intercept represent in the real world context? d) write your equation as a function of x. e) if you do not earn a college degree and you are earning minimum wage in 2020, what do you predict you will be earning per hour with the linear regression equation? f) if the trend continues, when will the minimum wage be $15 an hour? 3. why are your answers to #1d and #2a above different? which do you think is more accurate (#1 or #2) and why
