Dilation with scale factor of 3= E.
translation 3 units up= D.
translation 3 units right= B.
horizontal stretch by a factor of 3= A.
vertical stretch by a factor of 3= C.
translation= its move places, so you are adding
stretch= it changes shape. you can either stretch it horizontally or vertically so you are multiplying
going up and down/ vertically is the y-axis
going left and right/horizontally is the x-axis
hope this helped!
Answer:

Step-by-step explanation:
<em>Look at the picture.</em>
<em />
We have:

Therefore
<em>divide both sides by 2</em>

-3x-2y=10
-2y=3x+10
y=-3/2x -5
If you put x as a value of 0 you will get that the y-intercept will end up being -5
Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm
