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):
