Question

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).

Answer 1

Explanation:

Hey there!

The coordinates of a triangle are;

• A (1,2)
• B (1,-2)
• C (-2,-2)
• Scale factor = -4 and centre at (0,0)

Now, We have;

P(x,y)----------- P'(kx, ky)

Keep formula;

A(1,2)---------- A'(-4×1 ,-4×2)

= A'(-4, -8)

B(1,-2)------------- B'(-4,8)

C(-2,-2)-------------C'(8,8)

[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Hope it helps..
