What is the directional angle θ of vector b⃗ in the xy-plane measured counterclockwise from the x-direction?.

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

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
