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

Y = -x - 1 and y = 1/2x + k intersect at the point (-2,1). Find the value of k.

Lena [83]

Answer:

k = 2

Step-by-step explanation:

(-2,1) = (x,y) So you substitute -2 and 1 for x and y

1 = -(-2) - 1 1 = 1/2 × -2 + k

1/2 × -2 = -1 -1 + 2 = 1

k = 2 1 = 1/2 × -2 + 2
