Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
The slope of the line passing through two points can be found by using the formula
<h3>

</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question
The points are (-2,5) and (3/2, 2)
The slope is
<h3>

</h3>
We have the final answer as
<h3>

</h3>
Hope this helps you
The parent function
passes through the point
, since 
Your function passes through the point
, which means that the parent function has been translated 3 units up.
To translate a function vertically, you have to add a constant, i.e. you have to transform 
k is the amount of units you want to translate: positive if you translate upwards, negative if you translate downwards.
In your case, you move 3 units upwards, so you want k=3 and your function is

12b+3=-2b-4
12b+2b=-4-3
14b=-7/:14
b=-7/(14)
b=-1/2
