d) Use your equation to determine the value of the phone after in 2015 years. 9. This graph shows how Maria is snowboarding down the hill. On which segment is Maria go fastest? Why? On which segment will she go slowest. Why? Prove your answers to part a and b mathematically. ANALYTIC GEOMETRY SUCCESS CRITERIA I can identify the steepness and direction of a line by analyzing its slope The greater the of the m-value, the steeper the line magnitude A has a line rising to the right positive slope A line falling to the right has a negative slope has a and its equation has the form where b is the value of the A horizontal line slope of 0 y = b y - intercept A vertical line has an undefined slope and its equation has the form x = a, where a is the value of the x - intercept
