Answer:

Graph has a coefficient correlation r closest to -0.95 is the b).

Step-by-step explanation:

The correlation refers to the slope of a function and the sign indicates the direction to be linear the correlation informs us that it is inversely proportional

Taking some number  to realice

Y axis maximum 5

X axis maximum 5

Notice 5 is where cut axis y so b=5

Equation:

y=mx+b\\y=-0.95x + 5

Replacing:

x1=1.25; x2=2.5; x3=3.8;

So:

(1.25, 3.8); (2.5, 2.625); (3.8, 1.39)
