Please help

D cos (1/2 x )

Step-by-step explanation:

y = cos (x/2)

because from the graph x = 2pie

= cos pie = -1

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

according to egenuity the answer is

step-by-step explanation:
