Find the direction of the vector P Q → whose initial point is at and end point is at is at . The coordinates of the initial point and the terminal point are given. Substitute them in the formula tan θ = y 2 − y 1 x 2 − x 1 . Find the inverse tan, then use a calculator.

1.Apply the equation. to find the magnitude, which is 8.6.
2.Apply the equation theta = tan–1(y/x) to findthe angle: tan–1(–7.0/–5.0) = 54 degrees. However, note that the angle must really be between 180 degrees and 270 degrees because both vector components are negative
Hope it's help u
