Question

distance in the coordinate plane
#12:
z(1, - 2)
is reflected over the x - axis.
______ units
#12: coordinates after reflection:______

Explanation:

Step1: Recall the reflection rule over the x - axis

When a point \((x,y)\) is reflected over the \(x\) - axis, the rule is \((x,y)\to(x, - y)\).
For the point \(Z(1,-2)\), \(x = 1\) and \(y=-2\).

Step2: Apply the reflection rule

Using the rule \((x,y)\to(x, - y)\), substitute \(x = 1\) and \(y=-2\).
We get \((1,-(-2))=(1,2)\).

Answer:

\((1,2)\)
