Answer:
The coordinates of image are : (-3,4) , (-8,2) and (-4,7)
Explanation:
The rule is given as (x, y) —> (-x,y)
The coordinates of the triangle are : (3,4) , (8,2) and (4,7)
The coordinates of the image of the triangle will be : (-3,4) , (-8,2) and (-4,7)
Graphing the coordinates of image and connect the points to get the image of the triangle as attached below;
You will notice the rule of the transformation is a reflection along the y-axis.
