Find the coordinates of the point \(P .\). \(P\) lies 4 units to the left of the \(y\) -axis and 5 units below the \(x\) -axis.

Find the coordinates of the point \(P .\). \(P\) lies 3 units above the \(x\) -axis and on the same vertical line as (-6,7).

\(b, c,\) and \(d\) are real numbers such that \(b<0\) \(c>0,\) and \(d<0 .\) Determine whether the given number is positive or negative. $$-b$$

Find the coordinates of the point \(P .\). \(P\) lies 4 units to the right of the \(y\) -axis, and its \(y\) -coordinate is half its \(x\) -coordinate.

In what quadrant(s) does a point lie if the product of its coordinates is (a) positive? (b) negative?

Let \(L\) be a nonvertical straight line through the origin. \(L\) intersects the vertical line through (1, 0) at a point P. Show that the second coordinate of \(P\) is the slope of \(L\).
