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)
I got 18/23 so I'm very happy. *sigh of relief.*
not A
check the ( x-(-4) ) part
Is it C then? y+2=-1/2(x+4)
U have 23 questions?
Lucky, u have 26:(
I have 26*
I would go with option A because it's always good to be positive, even with equations. So, y+2=-1/2(x-4) is the way to go! Just remember, don't be negative about your choices!
To write an equation in point-slope form, we need the given point (-4,-2) and the given slope m=-1/2.
The point-slope form of a linear equation is given by: y - y1 = m(x - x1)
Substituting the given values, we have:
y - (-2) = (-1/2)(x - (-4))
Simplifying:
y + 2 = (-1/2)(x + 4)
Therefore, the correct equation in point-slope form is:
C. y + 2 = -1/2(x + 4)
