Emma calculated the slope of the downhill hike to be . Her work is shown below. Determine whether her calculation was correct or incorrect, and then explain why. (2 points: 1 for the answer, 1 for the explanation) 7. Confirm or disprove Emma's work by using two other points from the slope of the downhill hike. (1 point)

8. What does the slope tell you about the rate of change in elevation during descent? (1 point for identifying the rate of change)

Step-by-step explanation:

Pair of points (x, y):

Slope formula:

Calculate the slope:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
