Your answer should be a polynomial in standard form.

step-by-step explanation:

months on x axis

no. of subscriber on y axis

so we can write order pair as

(5,5730)   (7,6022)

slope =m = (y2-y1)/(x2-x1) =(6022-5730)/(7-5)=146

for writing equation we will use point slope form

y-y1 =m(x-x1)

y-5730=146(x-5)

y-5730=146x - 730

y=146x+5000

so after 10 month

y=146(10)+ 5000

y=6460

the answer is a -1.5
