how do you use desmos to find the line of best fit for a scatterplot after inserting the table? y1 = mx1 + b…

Brief Explanations:

In Desmos, when finding the line of best fit for a scatter - plot after inserting the table, the notation y1 ~ mx1 + b is used. Here, the ~ symbol indicates a regression (finding the line of best fit), and the subscript 1 refers to the data points from the table (where x1 and y1 are the columns of the inserted table). The other options:

• y1 = mx1 + b is just the equation of a line without indicating regression.
• y = mx + b and y ~ mx + b do not reference the data from the inserted table (lacking the subscript to link to the table columns).

Answer:

B. ( y1\sim mx1 + b )
