Question

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:

Answer 1

Slope=
`(1000)/(6)`

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.

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.
