Acity map is placed on a coordinate grid. the post office is located at the point
p ( 5, 35) , the library is located at the point l (15, 10) , and the fire station is
located at the point f  (9, 25) . what is the ratio of the length of pf to the length of
lf ?
a 2 : 3
b 3 : 2
c 2 : 5
d 3 : 5

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.
