y-y1=m(x-x1)
Here, it would be y+2=-2(x+6) or A.

Slope, m, is vertical change divided by horizontal change for any two points on a line.

Any two points, (x[i],y[i]) and (x[t],y[t]),
m=%28y%5Bt%5D-y%5Bi%5D%29%2F%28x%5Bt%5D-x%5Bi%5D%29
What if, you generalize more, dropping the subscripts for t:
m=%28y-y%5Bi%5D%29%2F%28x-x%5Bi%5D%29
m%28x-x%5Bi%5D%29=y-y%5Bi%5D
Symmetric Property of Equality gives
highlight%28y-y%5Bi%5D=m%28x-x%5Bi%5D%29%29, and the sub t variables are now unknown variables, while sub i variables are any given known variables.

Write the point-slope form of an equation for a line that passes through the point with the given slope.

(-6, -2), m = -2
Select one:
a. y + 2 = -2(x + 6)
b. y - 2 = -2(x + 6)
c. y + 2 = 2(x + 6)
d. y + 2 = -2(x - 6)
y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29, with:

x%5B1%5D being - 6

y%5B1%5D being - 2

m being - 2

Substitute and see what you get.
