A. The approximate y intercept appears to be about 1.8 (slightly less than 2). What this tells us is that someone with 0 months of practice could expect to win around 1.8 games.
B. Using slope intercept form and assuming that the y intercept is at (0, 1.8), the equation can be solved for by finding the slope first and then putting the slope and the y intercept into the equation.
Slope (m):
points (0, 1.8) and (1, 3.0)
(Y2-y1)/(x2-x1)=(3.0-1.8)/(1-0)=1.2/1=1.2
Equation:
Y=mx+b
Y=1.2x+1.8

Step-by-step explanation:
P=Peter. J=Juan
P=15+J/2
36=15+J/2
21=J/2
J=42 km
Answer:
27
Step-by-step explanation:
Given :
Total number of people : 36
Ratio of people who prefer red to blue
Red : Blue = 3 : 9 = 1 : 3
according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.
Expressed mathematically:
People who prefer blue = 3/4 of the total number of people
In our case, total number is 36 hence,
People who prefer blue (and hence the number of blue pens he should order),
= 3/4 x 36 = 27
