Since value of k is same for y/x for all values in the table so, y varies directly with x

And equation is: $y=-2.25\,x$

Step-by-step explanation:

We need to find if y varies directly with x from the values given in the table.

If y varies directly with x then we have the equation:

$y=k\,x$

where k is constant of proportionality

or we can write

$\frac{y}{x}=k$

If k is same for all values of x and y when (y/x=k) then we can say that y varies directly with x.

if x = -20 and y=45 then k is:

$\frac{45}{-20}=-2.25$

So, value of k is -2.25

if x = 1 and y=-2.25 then k is:

$\frac{-2.25}{1}=-2.25$

So, value of k is -2.25

if x = 12 and y=-27 then k is:

$\frac{-27}{12}=-2.25$

So, value of k is -2.25

Since value of k is same for y/x for all values in the table so, y varies directly with x

And equation is: $y=-2.25\,x$

Answer:

<h2>first blank:</h2><h2>c=sqrt(a^2+b^2)</h2><h2>second blank:</h2><h2>c=sqrt((8-2)^2+(-5-3)^2)</h2><h2 />

Step-by-step explanation:

c^2=a^2+b^2

sqrt(c^2)=sqrt(a^2+b^2)

c=sqrt(a^2+b^2)

c=sqrt((x2-x1)^2+(y2-y1)^2)

c=sqrt((8-2)^2+(-5-3)^2)
