Which expression is equivalent to -18a^-2 b^5/-12a^-4 b^-6? Assume a doesn’t =0, b dosnt =0

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
