Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Question
Basically I have this math assignment, in which I’m confused about. I highlighted the preferred section that I would like assistance on. But if you are able can you let me know if I got the first part of the question right. So if I listed the right two lines of fit passes through. And what is the slop of the line. I attached the assignment and the graph.

means.
The correlation indicates that the number
of miles travelled by a car has a negative
relationship with its value. This is
because the line descends based on the
plotted points. The number of miles
driven increases as the value of a car
decreases.
Positive Correlation
Negative Correlation
No Correlation
Verify that the slope is correct.
List two points that the line of fit passes
through and find the slope of the line.
Check that your slope matches your
correlation. (A graph with a negative
correlation should have a negative slope.)
