Seriously need help on this problem

Answer:
y = -1/2(x -2) -4
Step-by-step explanation:
When you are given a slope and a point, the point-slope form of the equation of a line is useful. For slope m and point (h, k), it is usually written as ...
y -k = m(x -h)
I like the version with k added:
y = m(x -h) +k
Filling in your given values, m = -1/2, h = 2, k = -4, the equation for your line is ...
y = -1/2(x -2) -4
You can simplify this to ...
y = -1/2x -3
