Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:
4 = −6⁄7[2] + b
−1 5⁄7
_______________________________________________
10 = −6⁄7[−5] + b
4 2⁄7
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

Answer:
Q1 = 61
Q3 = 63
Step-by-step explanation:
From the plot attached :
Data obtained is :
Temperature frequency
59 0
60 2
61 3
62 3
63 4
64 2
65 1
Frequency Total 15
Data in raw format :
60,60,61,61,61,62,62,62,63,63,63,63,64,64,65
The first quartile :
Q1 = 1/4(n+1)th term
n = 15
Q1 = 1/4(15+1)th term
Q1 = 1/4 * 16th
Q1 = 4th term
Q1 = 61
Third quartile (Q3):
Q3 = 3/4(n+1)th term
n = 15
Q3 = 3/4(15+1)th term
Q3 = 3/4 * 16th
Q3 = (48/4)th term
Q3 = 12th term
Q3 = 63
