To break the school's record, the boys' time had to be faster than 7 2 12 minutes. Estimate to decide if the boys broke the record. If so, how much faster were they? If not, how much slower were they? Explain

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.

x coordinate is none

step-by-step explanation:

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
