Graph the image of the given triangle after the transformation that has the rule (x, y)→(−x, −y) .

By the given graph,

The vertices of the triangle are,

(7,4), (-2,5) and (6,7),

Given rule of transformation,

Thus, under this transformation, the vertices of the transformed triangle would be,

(-7,-4), (2, -5) and (-6,-7)

Plot these points on the given graph,

After joining them we will get the graph of the transformed triangle ( shown below )

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
