Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

\frac{y_2-y_1}{x_2-x_1}

The given relation is

X : -2 , -3, -4, -5  

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.

True or false:in a geometric sequence, the term a(n+1) can be smaller than the term a(n)
Svetllana [295]
A(n) = current term

a(n + 1) = next term

in a geometric sequence, the next term comes from a product of the current term and the common ratio.

the common ratio can be any value, let's say use r = ½.

if the current term is say hmmm 40, the next term is 40*½ , or 20, so indeed, the next term is smaller.
