Answer:
Below in bold.
Step-by-step explanation:
The 2 points are (-2, 4) and (2, 2).
a. The slope = difference in y values / difference in x values
= (4 - 2) / (-2-2)
= 2 / -4
= -1/2.
b. The slope of a parallel line is the same so it's -1/2.
c. The relationship between perpendicular lines is as follows:
If the slope of a line = m then the slope of a perpendicular line is -1/m.
So here it is - 1 / -1/2
= -1 * -2
= 2.
