A restaurant sells pizza for the prices in the data table. Calculate the linear regression equation of the data.
y = 1.5x + 12
y = 12x + 1.5
y = 0.67x - 8
y = -8x + 0.67
Find the equation of the line of best fit for the given data
y = 163.41x+1.49
y =- 163.41x+ 4.19
y =- 4.19x+163.41
y = 4.19x -163.41
Write the linear regression equation for the following data points. Round to the nearest tenth.
y=−0.27x+3.93
y=3.93x+−0.27
y=1.25x+3.75
y=0.27x+3.94
Which scatter plot diagram shows the strongest positive correlation?
The annual profits for a company are given in the following table, where x represents the number of years since 1992, and y represents the profit in thousands of dollars. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth.
