Which equation shows how (-10, 8) can be used to write the
equation of this line in point-slope form?
oy-8 = -0.15(x - 10)
y + 8 = -0.15(x - 10)
oy-8= -0.2(x + 10)
y + 8 = -0.2(x - 10)

For this case we have that by definition, the equation of a line in the point-slope form is given by:

Where:

m: It is the slope of the line

: It is a point that belongs to the line

According to the statement we have the following point:

Substituting we have:

Thus, the most appropriate option is option C. Where the slope is

Option C
