Question

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)

Answer 1

Can you write a generic point slope form?

If it passes through the point (a,b) and has slope "m", what might you create?

Answer 2

I really don't know

Answer 3

Okay, but you have to do better than that. You WILL BE required to know this on examination.

Point Slope: (y-b) = m(x-a)
If we are given the point (a,b) and the slope m.

Can you substitute the three values from your problem and see what we get?

Answer 4

2, 1/2, 4?

Answer 5

a = -4
b = 2
n = -1/2
