Answer:

1. A. x-axis
2. B. right 4 up 12

Step-by-step explanation:

1. The horizontal number line is called the x-axis. The vertical number line is called the y-axis. The point where the x- and y-axes meet is the origin.
2. If you were to plot the point (4,-12), the correct method is to plot the point 4 units right, then 12 units down .

If you were to plot the point (4,-12), the correct method is to plot the point 4 units right, then 12 units down.

Option C is correct.

If a point is expressed in the form (x, y), the coordinate x represents the location of the point on the horizontal axis while the coordinate y represents the location of the point on the vertical axis.

If x is positive, it means that the point is plotted on the right hand side of the horizontal axis. If x is negative, it means that the point is plotted on the left hand side of the horizontal axis.

If y is positive, it means that the point is plotted on the top region of the vertical axis. If y is negative, it means that the point is plotted on the bottom region of the vertical axis.

For the point (4, -12)

x = 4, and y = -12

Since x = 4 is positive, the graph is plotted 4 units to the right.

Since y = -12 is negative, the graph is plotted 12 units down.

Therefore, If you were to plot the point (4,-12), the correct method is to plot the point 4 units right, then 12 units down.
