The equation of the scatter plot is (a) y = 100x + 2
<h3>How to determine the equation of the scatterplot?</h3>The line of best fit of the scatter plot passes through the points
(x,y) = (0,2) and (1,102)
Start by calculating the slope using:
So, we have:
m = 100
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 100(x -0) + 2
Evaluate
y = 100x + 2
Hence, the equation of the scatter plot is (a) y = 100x + 2

Answer:
10 miles per hour.
Step-by-step explanation:
Let x represent athlete's walking speed.
We have been given that her jogging rate is 5 mph faster than her walking rate, so athlete's jogging speed would be miles per hour.
10 minutes = 1/6 hour.
20 minutes = 1/3 hour
While walking, we will get
While jogging, we will get
Since athlete is covering same distance while walking and jogging, so we can equate both expressions as:
Cross multiply:
Therefore, athlete's walking speed is 5 miles per hour.
Jogging speed:
Therefore, athlete's jogging speed is 10 miles per hour.
