Step-by-step explanation:
If a line that passes through the point
and it has slope
, the equation of the line is:

Answer:12
Step-by-step explanation:
Answer:
<u><em>Part A:</em></u> D. 
<u><em>Part B:</em></u> C. 
Step-by-step explanation:
For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.
The equation: 
Now plug in 0 for x.

Now solve.
y = (1)(3)
y = 3
This proves that this is the correct answer.
For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.
The equation: 
Now plug in x for 0 and solve:



This equation is true, now we check for the other value of x, 3.



This is also true so that means this is the correct answer.
is the factored form of 
<em><u>Solution:</u></em>
We have to factor the given expression

We can use the algebraic identity to factor the given expression

Lets make the given expression in form of 


Now apply the algebraic property in above expression
Here, a = 2x and b = 3y
Therefore,


Thus the given expression is factored out
