Answer:
Step-by-step explanation:
Let
w ----> the amount of weight lost in pounds
we know that
The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week
so
The linear equation that represent this situation is
solve for w
subtract 2,312 both sides
Question: (a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Answer:
Given equation is y = 6x + 8.
Where y represents the number of baskets of berries the workers picked over a period of time x in hours.
Compare with slope intercept form y=mx+b, we get m=6 and b=8
Hence slope is 6 and y-intercept is 8.

Question: (b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
Answer:
Rate of change means slope so answer is 6.
Initial amount means y-intercept so that is 8.
rate of change of 6 means six baskets of berries are picked by workers in 1 hour.
Initial amount of 8 means there was 8 baskets of berries already filled in the beginning.

Question: (c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Answer:
first we graph y-intercept that is at point (0,8)
slope = 6 means make another point which is 6 unit up then 1 unit right from (0,8) so the new point is at (1,14)
Hence final graph is the line joining both points.
