Answer:
Absolute value is the distance on a number line. In other words, a number with absolute value will always be positive.
Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
Given:
The matrix equation is:

To find:
The value of matrix C.
Solution:
Let
. Then the given equation can be rewritten as




On substituting the values of the matrices, we get




Therefore, the correct option is C.
