A climber is on a hike. After 2 hours he is at an altitude feet. After 6 hours, he is at an altitude of 700 feet. What is the average rate of change?
The average rate of change for the climber is 75 feet every 4 hours

Write in standard form: y = -3x+5
3x+y= 5
15
Convert to standard form : y= -3/2x + 8
3x+2y = 16
15
Identify slope and y-intercept: y = 1/2x+7
m= 1/2; y-intercept = (0, 7)

The average price of a movie ticket in the year 2001 was $6.39. The average price of a movie ticket in the year 2005 was $7.39. Assuming the increase is linear, what would be the approximate price of a movie ticket in the year 2010?
In 2010, the movie ticket will be $8.64 (increasing at $.25 cents per year or $1.00 every four years.

Determine the function and explain why: 2x+8y = -24
Linear because it is in standard form.
15
Find the slope: (0, -1) & (5, -8)
m = -7/5
15
Look at the picture and solve, you will then draw the line:
m= 1/2; slope = (0, -1)
