Find the equation of the line of best fit. The shop owner says "We sell more bowls of soup the higher the temperature". Does the scatter graph support this statement? Give a reason for your answer.
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.

On graph paper, draw a scatter plot of temperature against bowls sold to represent the data using a scale of 1 cm to represent 5 bowls and 2cm to represent 5°C.
ii.
Write down the type of relationship between the variables.
iii. Calculate the mean number of bowls of soup, x, sold.
Find the mean maximum temperature, y of soup recorded.
1v.
Plot and label the point M (x, ỹ ) on your graph.
V.
V1.
The line of best fit for the data passes through the point M and the y-intercept (0, 33.2). Draw this line on your graph.
vii. Find the equation of the line of best fit.
viii. On another day of the year, the temperature was 20°C. Using the equation of the line of best fit, estimate the number of bowls of soup sold on that day.
1X.
