Which representation has a constant of variation of -2.5
x : -2 , -3, -4, -5
y : -5, -7.5,-10,-12.5

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

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

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.
