I believe it is the commutative property, hope this helps!
Let n be the man's walking rate. Then:
9/n+9/27=3&1/3
243+9n=90n
243=81n
n=3
The man's walking rate was 3 mph

Answer:
y=4/3x-1/3
Step-by-step explanation:
m=y2-y1/x2-x1
fill in the two points for the y's and the x's
then proceed to y = mx+b
Where:
m is the slope, and
b is the y-intercept
then you solve and <u>bam</u>!
