The slope of the line is 4.83 and the y-intercept is 51
<h3>How to determine slope and the y-intercept?</h3>
From the graph, we can see that the line of the best fit touches the y-axis at y = 51
This means that:
The y-intercept is 51
The slope is then calculated as:
m = (y2 - y1)/(x2 - x1)
Using the points on the line, we have:
m = (80 - 51)/(6 - 0)
Evaluate
m = 4.83
Hence, the slope of the line is 4.83

Hope that answers your question
Step-by-step explanation:
In this question all required information's are already provided. Based on these details the answer to the question can be easily determined. Let us now write down all the information's that are already given.
Mass of the roller coaster = 1000 kg
Velocity of the roller coaster = 20.0 m/s
We know the formula for finding the kinetic energy is
Kinetic energy = 0.5 * mass * (velocity) ^2
= 0.5 * 1000 * (20)^2
= 0.5 * 1000 * 400
= 200000 Joules
So the Kinetic energy of the roller coaster is 200000 joules.
It would be 11 squares by 8 squares. The area would be 88.
