Which equation represents a direct linear variation? a. y = x + 3 b. y = x2 c. y = 1/x d. y= 1/5xwhat is the direct linear variation equation for the relationship?   y varies directly with x and y = 4 when x=12a. y = x+8 b. y= 3xc. y= 1/3x     d. y= x-8   

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
