The answer would be C I hope that helps
Answer:
7a) y = 
b) this equation means that for every 5 minutes the tram is an additional 1,273 feet above base
c) the first quadrant has 'x' and 'y' values that are positive and only positive values can be used to represent elevation above base and time
Step-by-step explanation:
Answer:
a) 12 points
b) A: 3 questions; B: 2 questions
Step-by-step explanation:
The least number of points each section may have is the least common multiple of 4 and 6. That is a number that will have all of the factors of 4 and all of the factors of 6: 2×2×3 = 12.
<h3>a)</h3>
Each part is worth 12 points.
<h3>b)</h3>
Part A has 12/4 = 3 questions.
Part B has 12/6 = 2 questions.
P = 3
n = 5
N = 15

To find the slope,we can use the slope formula:

Where x and y are y coordinates and x coordinates respectively.
To find the answer, put any two points into the formula.
In this case, (1,5) and (0,-1) will be used:
x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

Therefore the answer is 6.
Hope it helps!
