4. A friend is planning to sell her used Honda so she gathers data on prices (in thousands of dollars) and year (let 79 represent 1979) for eleven cars similar to
hers. A scatterplot of the data is shown. The linear regression equation for these
data has the equation: price=0.735-year-59.5. Your friend's Honda is a 1988. Use
the regression model to establish a selling price for her car.

price = 0.735 . year – 59.5; r2 = 0.87

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
