Answer:
Part A: Option A
Part B: Option C
Step-by-step explanation:
Given two points (7, 5) and (21, 15)
we have to find the slope of the line passing through above two points.
The slope of line can be calculated as
Option A is correct.
Part B: Also given another line with a slope that is one-third that of the slope of above and passes through the origin and the point
we have to find the point.
The equation of line becomes
The point which satisfies the above equation passes through the line.
Not satisfied
Not satisfied
Satisfied
Not satisfied
Hence, the line passes through the point (21, 5)
Option C is correct.

We have to remember that absolute value functions have the following form:
It means that there is a positive and a negative slope lines,
Let's find the information that we need to graph a absolute value function:
First:
Finding the y-intercept,
So, the y-intercept is (0,2)
Second:
Finding the two lines intercepts,
if x ≥ 0
if x< 0
Therefore,
If , we have that:
So, both lines intercepts at (0,2).
