Answer:

The slope is -2/25.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(14-18)/(30-(-20))

m=-4/(30+20)

m=-4/50

simplify

m=-2/25

HEY LOL PLEASE ANSWER THESE. PLEASE IM BEGGING YOU. HELP ME
Alexandra [31]

Answer:

a. ∆ABC ~ ∆A'B'C'

b. Enlargement

c. Scale factor = 4

Step-by-step explanation:

a. <A corresponds to <A'

<B corresponds to <B'

<C corresponds to <C',

Therefore, the similarity statement would be: ∆ABC ~ ∆A'B'C'

b. The image of the dilation is an enlargement of the original figure because the side lengths of ∆A'B'C are larger than the corresponding side lengths of ∆ABC.

c. Scale factor = the ratio of the corresponding sides

Thus:

Scale factor = A'B'/AB = B'C'/BC = A'C'/AC

Scale factor = 24/6 = 48/12 = 60/15 = 4

Scale factor = 4
