Keisha is working on a math worksheet with 50 problems. she has completed 20 problems in 25 minutes. if she continues at the same pace, what will the total time be for her to complete the worksheet?

a) 31.25 minutes
b) 62.5 minutes
c) 70 minutes
d) 75 minutes

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.

i will pick c put check it over to be sure
