Step-by-step explanation:
The constant of variation is found using the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
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
[tex]m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5[/tex]
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.
