To find the slope of the line, choose any of the points in the table and set up this expression:
y2 - y1 / x2 - x1, where y2 is the y coordinate of the second point you chose, y1 is the y coordinate of the first point you chose, x2 is the x coordinate of the second point you chose, and x1 is the x coordinate of the first point you chose.
So,
3 - (-6) / 2 - 2 = 9 / 0 for the first two points. The slope of the line is undefined because it is a vertical line.
Answer:
5t = 4b
Step-by-step explanation:
Here, we want to write a proportional relationship for b in terms of t
From the question, b represent the amount of candle burned away in a given time t hours
From what we have initially, 13 3/4 burnt in 11 hours
So in 1 hour, the amount burnt will be;
55/4/11 = 5/4
5/4 inches of candle burnt in 1 hour
5/4 inches = b/t
So b inches burnt in t hours
5/4 = b/t
5t = 4b
The answer for the picture would be 21
1.19 - 19%
