Question

if triangle abc is reflected across the x - axis, what are the coordinates of point a? if triangle abc is reflected across the x - axis, what are the coordinates of point b? if triangle abc is reflected across the x - axis, what are the coordinates of point c? (3,1) (1,3) (1,0)

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected across the $x - axis$, the rule is $(x,y)\to(x, - y)$.

Step2: Identify original coordinates of point C

From the graph, assume the original coordinates of point C are $(1, - 3)$.

Step3: Apply reflection rule

Using the rule $(x,y)\to(x, - y)$, for point C with $x = 1$ and $y=-3$, we get $(1,-(-3))=(1,3)$.

Answer:

$(1,3)$
