PLEASE HELP! I know the top part I just need the bottom!
Zolol [24]

slope  = (y2-y1)/(x2-x1)

        = (70-52)/(8-1)

    = 18/7

=2.6

point slope form

y-y1 = m(x-x1)

y-52 = 2.6(x-1)

distribute

y-52 = 2.6x-2.6

add 52 to each side

y = 2.6x+49.4

y = 2.6x +49


the initial temperature is 49.4 or about 49

and it increases about 2.6 degrees each week
