How to graph -x + 2y = 6
larisa86 [58]
In order to graph the equation, you need some coordinates, 
So, put x = 0, 
2y = 6. y = 3.  Coordinate = (0, 3)

Now, put y = 0, 
-x = 6
x = -6   Coordinate (-6, 0)

In short, Just mark that two points and draw a line, graph is done

Hope this helps!

IRINA_888 [86]

Answer:

0.95

Step-by-step explanation:

Correlation \ coefficient \   (r) = \dfrac{covaraince \  between \ X \ and \ Y }{SD_X \times SD_Y }

Correlation \ coefficient \   (r) = \dfrac{15 }{10^{1/2} \times 25^{1/2} }

Correlation \ coefficient \   (r) = \dfrac{15 }{3.162 \times 5 }

Correlation \ coefficient \   (r) = \dfrac{15 }{15.81 }

Correlation \ coefficient \   (r) \simeq 0.95
