Which value of c would make he following expression completely factored? 8x+cy

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable.
