In point slope form, required equation is given by (y - y1) = m(x - x1); where m = (y2 - y1)/(x2 - x1) = (4 + 1)/(8 - 2) = 5/6
Required equation is y + 1 = 5/6 (x - 2)
In standard form, 6y + 6 = 5x - 10 => 5x - 6y = 6 + 10 => 5x - 6y = 16
Answer:
x=4
Step-by-step explanation:
7-2x=2(x-4)-1
7-2x=2x-8-1
7-2x=2x-9
7+9=2x+2x
16=4x
x=4
59, 51, 53
The formula you would use is
x+(x+2)+(x+4)

Solution: We have to find the Frequency and Relative frequency of the given data:
Frequency is the number of times a number occurs.
Relative Frequency is the number of times a number occurs divided by the total number of items.
Therefore, the frequency and relative frequency are calculated as below:
Number Frequency Relative Frequency
20 1 
21 4 
22 2 
23 4
24 3 
25 2 
26 3 
27 5 
28 3 
29 4 
Total 31
12,176/24 = 1522/3 or 507 1/3
