Write an equation in point -slope form for the line through the given point with the given slope
(-4,-2); m=-1/2

a. y+2=-1/2(x-4)
b. y+2=(-1/2)x-4
c. y+2=-1/2(x+4)
d. y-2=-1/2(x-4)
what would the answer be? i’m not the best in math.

This is about circle theorems. someone asap : (

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
