Answer:
b
Step-by-step explanation:
Subtract 4 and 1
4-1=3
distance or length of this line segment is 3
Answer:
Step-by-step explanation:
First choose two points on the line,
Let the points are A and B.
From point A to B we are moving downwards by (5 - 1 = 4 units)
Therefore, Rise = -4
Horizontal distance between A and B = 2 units
Therefore, Run = 2
Since, slope of a line = 
Slope = 
= -2
