Two parallel lines are graphed on a coordinate plane as shown. The lines are rotated about the origin. The graph of the image of the lines after the rotation is also shown. Which conclusion is supported by the image of the liens? A. When parallel lines are rotated, the images of the lines are always parallel. B. When parallel liens are rotated, the images of the lines are always perpendicular. C. When parallel lines are rotated, the images of the lines always have the same as the original lines. D. When parallel lines are rotated, the images of the lines always have the same - y- intercept as the original liens.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
