Question

the scatter plot shows the relationship between a car salesmans average daily sales and weekly earnings. determine the slope and y-intercept of the line of best fit for this data.
car sales and wages
weekly earnings (in $)
number of cars sold daily
the y-intercept of the line of best fit is
which means
the slope of the line of best fit is
which means
options for y-intercept: 1000, 1100, 0, 102
options for slope: (associated meaning options, partially visible)

Explanation:

Step1: Identify two points on line

Assume two clear points: (0, 1000) and (1, 1102)

Step2: Calculate slope

Slope formula: $\frac{y_2 - y_1}{x_2 - x_1} = \frac{1102 - 1000}{1 - 0} = 102$

Step3: Find y-intercept

y-intercept is y when x=0, which is 1000

Answer:

The y-intercept of the line of best fit is 1000
The slope of the line of best fit is 102
