Answer:
A. 
Step-by-step explanation:
Let 
be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is 
Hence,
is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:
Therefore, the equation of the line is

Answer: 17/50
Step-by-step explanation:
First, to add fractions, we must find a common denominator, in this case, 100.
Then, we must make the fractions being added all have the common denominator.
So, we must multiply 3/10 * 10/10, which equals 30/100
30/100 + 4/100
Then, just add across the numerator to get 34/100, which can be simplified to 17/50
