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.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
