Step-by-step explanation:
It is multiplication property of equality. The goal is to get d by itself so what we do here is basically a process of

1. 6.5, 2. 22.4, 3. 10 and 11, 4. 6 and 7, 5. between 8 and 9 but closer to 8
Vertical lines have undefined slope. They are not y=mx+b equations, but simply x= equations.
This line passes through the point (-1,12) has an x-value of -1. Therefore the equation of the line is simply x=-1
Answer: b=2
Step-by-step explanation: First you will have the equation 22=11b. You need to get b by itself so you will need to divide each side by 11 which will leave you with 22/11=11/11b. After that you will be left with 2=b
Answer : 0.497 is what i think it is
