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.

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
