Alright, so in this you're going to want to set the ratios equal as follows:
2/12 = x/18
Therefore by cross-multiplying:
2*18 = 12x
36=12x
36/12=x
x=3
The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.
We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.
From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>
ANSWER: -0.91
Answer: the zeros are -3, -3 and 5
Multiplicity is 2
