Answer:
Slope of the line that passes through the points (1, 7) and (3, 3) = -2
Step-by-step explanation:
Given in the question two co-ordinates,
(1, 7)
(3, 3)
here x1 = 1
x2 = 3
y1 = 7
y2 = 3
Formula to use
m = 
= 
= -4/2
= -2
I think false.
.
Velocity the speed AND direction of something.
.
you run AROUND a track, so the direction changes. Thus velocity changes.
Answer is 0.75
0.75 x 100= 75
