The graph shows the relationship between Ed's hiking time and the altitude on
the one day he hiked up Glacier Peak. The equation for the graph is
y= 1000 x + 4000.
Slope =

Interpret slope:

Y-intercept =

Interpret y-intercept:

Slope=

Interpret slope: This is the m in the equation so that is the slope. This means that Ed is traveling 1000 feet every 6 hours.

Y-intercept= 4000

Interpret y-intercept: This is the b in the equation so it is the y-intercept. This also means that he is starting at 4000 feet when he started to hike.

Step-by-step explanation:

Slope is rise over run. The hours are the run and the distance is the rise. So for every 6 hours they are traveling 1000 feet. You find the y-intercept by plugging in 0 for x when given the equation. Sine you have the graph, you look along the line y=o to find 4000 ad the intercept.

The correct answer is A, smaller than the size you started with. Because you increased the size by 30% of the original page, and then took 30% of the larger page, you're taking more away than you increased it by. For instance, if you had a page that was 60 units², and you increased it by 30% (18 units), you would get 78 units². However, if you took 30% of 78 (23.4) and subtracted it, you would get 54.6 units², which is smaller than 60 units².

Hope this helps!
