B) 6

Step-by-step explanation:

convert mixed fractions to improper

multiply numerators 15*3 and denominators 2*5 where you multiply fractions

find a common denominator, 10. for 3/2, multiply top and bottom by 5.

 <= reduced to lowest terms

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.
