Urgent geometry dilations bogus answers will be reported

Divide the coordinates of Q' by the corresponding coordinates of Q to find the scale factor. The multiply the coordinates of R by the same scale factor to find the coordinates of R'.

Q(-3, 4) and Q'(-27, 36)

-27/(-3) = 9; 36/4 = 9 The scale factor is 9.

Now apply the scale factor to the coordinates of R to find the coordinates of R'.

R(-2, -1) ---> R'(-2 * 9, -1 * 9) = R'(-18, -9)

R'(-18, -9)

the answer is 15% decrease

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
