The chart shows the damage index to a head gasket on trucks according to ambient temperature. Draw a scatterplot of the data.

Which equation is closest to the line of best fit?
A) y = 14 x - 2/3
B) y = -14 x + 2/3
C) y = -2/3 x + 14
D) y = 2/3 x - 14

Answer 1

C. I would recommend that he does not go as lower temperatures have a strong negative correlation, therefore the lower the temperature the more damage is caused

Explanation:

The correct answer is I would recommend that he does not go as lower temperatures have a strong negative correlation, therefore the lower the temperature the more damage is caused. For temperatures below 19 degrees Celsius the scatterplot forms a negative correlation.

Answer 2

If we take a look at the data presented in the chart we can see the damage that the head gasket on truck suffers according to the ambient temperature. The correct answer is letter C) because there is a negative slope that is less than one and the y-intercept begins 14 units up the y-axis.

I hope this helps, Regards.
