The line x = -2 is a vertical line passing through point (-2, 0) on the x axis.
The set of points satisfying x = -2 are all the points on the coordinate plane which lies on the vertical line crossing point -2 on the x-axis.
Part B:
The line y = 5 is a horizontal line passing through point (0, 5) on the y axis.
The
set of points satisfying y = 5 are all the points on the coordinate
plane which lies on the horizontal line crossing point 5 on the y-axis.
Part C:
The line x = 0 is the y axis.
The
set of points satisfying x ≥ 0 are all the points on the coordinate
plane to the right of the y-axis.
Part D:
The
set of points satisfying xy > 0 are all the points on the coordinate
plane which lies on the 1st quadrant and all the points on the coordinate
plane which lies on the 3rd quadrant.
Part E:
The line y = 0 is the x axis.
The
set of points satisfying y < 0 are all the points on the coordinate
plane that are below the x-axis.
Part F:
The line x = 0 is the y axis.
The
set of points satisfying x = 0 are all the points on the coordinate
plane that lie on the y-axis.
Part G:
The line y = -2 is a horizontal line passing through point (0, -2) on the x axis.
The
set of points satisfying y = -2 are all the points on the coordinate
plane which lies on the horizontal line crossing point -2 on the y-axis.
Part H:
The line x = 4 is a vertical line passing through point (4, 0) on the x axis.
The
set of points satisfying x = 4 are all the points on the coordinate
plane which lies on the vertical line crossing point 4 on the x-axis.
Part I:
The
set of points satisfying x / y < 0 are all the points on the coordinate
plane which lies on the 2nd quadrant and all the points on the coordinate
plane which lies on the 4th quadrant.
Part J:
The line xy = 0 are the x-axis and the y-axis.
Therefore, the
set of points satisfying xy = 0 are all the points on the coordinate
plane which lies on the x-axis and all the points on the coordinate
plane which lies on the y-axis.
Part K:
The line y = 1 is a horizontal line passing through point (0, 1) on the y axis.
The
set of points satisfying y > 1 are all the points on the coordinate
plane which lies above the horizontal line crossing point 1 on the y-axis.
Part L:
The line y = 0 is the x axis.
The
set of points satisfying y = 0 are all the points on the coordinate
plane that lie on the x-axis.
The original expression here might be (4x3) + (4x3). This is because the
distributive property simply moves around numbers, but will not change
the value of the equation, as in the question we are looking at here.
