Can someone please help me with an explanation of this? Show how you use the information on the graph to calculate the scale factor. Give the formula and show the work of plugging in numbers from the graph.
Question:
What is the scale factor for the dilation below?
Options:
1. 1/4
2. 1/2 (correct answer)
3. 2
4. 4

it's d

step-by-step explanation:

none.

step-by-step explanation:

b=-1

find the slope and y-intercept of the second equation.

b=-6

compare the slopes

m of the two equations.

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

m1=5,m2=0

it would rotate about 180 degrees.
