The Soluton:
Given:

We are asked to evaluate the given expression.
Explanation:
Since the number you are taking away is greater than thenumber that you want to taake it away from, we have to swap the numbers and then the result will be a negative number.
Therefore, the correct answer is -3.64
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
