In the $xy$  coordinate plane, if one takes the x-coordinate of a point in the first quadrant and a y-coordinate of a point in the third quadrant and multiplies them together, the answer will be:

What is the slope of line $y=-3x+2$ if reflected across the x-axis?

The circle with a center C and the right triangle ABC intersect the x-axis at point B and the y-axis at point A.  The length of the hypotenuse of  $\Delta ABC$   is  $6\sqrt{2}$  .  What is the equation of circle C?

If $g\left(t\right)=2t+2$ is graphed in the  $xy$   coordinate plane and is shifted up 3 units and to the left 4 units, what equation would represent the new function?

A triangle is formed by the line $x=3$ , which its longest side overlaps, and 2 other lines, one of which has a slope of 1 and the other of which is perpendicular to the line with the slope of 1.  Which of the following could be the lengths of the 2 shorter sides of the triangle?

What is the closest approximation of the fraction of all points in the $xy$ plane that would satisfy the expression $y\ge2x+1$  or $y\le-\frac{1}{2}x-1$  ?
