Answer:

f(x)could also be written as y in y= mx+ c

by taking two points we are gonna calculate.

(0,1), (4,-1)

finding m

y*- y'/x*-x'

=1-(-1)/0-4

=2/-4

=-2

now c ( intercept)

take any point

eg. (0,1)

y=mx+c

1=-2×0+c

1=c

equation then equals to

y=-2x+1

f (x) =-2x+1

Answer:

Easter, Christmas, birthdays, and New Year

Step-by-step explanation:

For me, I would choose Easter because before easter we always go to a church and stay there whole night. After 3-4 a.m, we go home and take a nap. But the most fun activity that we do during Easter is playing a game where we pick the best eggs and beat with each other. Later, our parents hide eggs and a couple of toys in the park and me and my siblings begin finding them.
