Answer:
Refer to the Attachment
Step-by-step explanation:
Rewriting the fractions in decimal and whole number, we have the following:


Thus, 42/3 is on 14 and 25/3 is on 8 and then add 1/3 from 8 going to 9.
Therefore, the points must be plotted as follows:
The blue point indicates the 42/3 while the red point indicates the 25/3.
X = first number
x - 8 = 2nd number
5x = 3rd number
x + x - 8 + 5x = 69
7x - 8 = 69 <=== this is the equation u would use
7x - 8 = 69
7x = 69 + 8
7x = 77
x = 11
1st number = 11
2nd number : x - 8 = 11 - 8 = 3
3rd number : 5x = 5(11) = 55
You want to isolate the variable 'y'.

Subtract 10 to both sides:

Divide -3 to both sides:
Answer:
C. x = 1
Step-by-step explanation:
When we have an undefined slope, we have a vertical line of x = [a number]. This isn't a function and we have an undefined slope because we don't know what m equals in y = mx + b.
