Afootball team gained 35 yards on a first down, lost 15 yards on the second down and gained 12 yards on the third down. how many yards do they need to gain on the fourth down to have a ten yard gain from their starting position?

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.

step-by-step explanation:

abc

the answer is 40.

proof:
