Answer 1

-0.93

Explanation:

As mentioned by Nicolas above, the line of best fit should give a negative coefficient because as x increases, y decreases.

Furthermore, since the lines do not make a perfect line, it cannot be the perfect fit, or a correlation of -1.00.

So we choose a negative answer but not -1.00 as explained previously. That lease the only choice of -0.93, by elimination without doing any calculations.

Answer 2

The answer is either (3) or (4) because drawing a line of best fit and finding its gradient is going to give you a negative answer
