What is the domain and the range of the relation represented by the ordered pairs? {(6,6),(−1,3),(3,6),(0,4)}{(6,6),(−1,3),(3,6)

Hello,
Let's review: The domain is all the possible x values of a relation/function. To get the domain, we look at the x values in the ordered pairs.
The domains are: {-1, 0, 3, 6} - as you can see these are the x values of each pair.
Let's review: The range is all the possible y values in a relation/function. To find the rang, we look at the y values of the pairs.
The ranges are: {3, 4, 6} - notice how there are two "6" in those pairs, and when writing the range, you don't need to repeat the number if it's already written.
I hope this helps! =)

Slope is positive with a y intercept at (0,-5) hope this helps
"3 miles below sea level" may be written as -3. The negative indicates you are below sea level. Going above sea level means the value would be positive.
"earning 45 dollars" can be written as +45 or simply 45. If you lost 45 dollars, then it would be -45. If you are in debt 45 dollars, then it would be -45.
"moving back 5 spaces" is represented by -5 whereas moving forward 5 spaces is +5 or simply 5.
25/50 * 16/32
1/2 * 1/2
= 1/4
we know that
1) scale factor is equal to 
2) The ratio of the perimeters of the triangles is equal to the ratio of the measures of the sides
3) the longest side of ∆ABC=[scale factor]*the longest side of ∆DEF
the longest side of ∆ABC=
the longest side of ∆ABC=
units
the answer part a) is
the longest side of ∆ABC is units
Part b)
The ratio of the area of ∆ABC to the area of ∆DEF is equal to the scale factor squared
so
![[scale factor]^{2} =(\frac{1}{10})^{2} \\ \\ =\frac{1}{100} \\ \\ =0.01](https://tex.z-dn.net/?f=%20%5Bscale%20factor%5D%5E%7B2%7D%20%3D%28%5Cfrac%7B1%7D%7B10%7D%29%5E%7B2%7D%20%5C%5C%20%5C%5C%20%3D%5Cfrac%7B1%7D%7B100%7D%20%5C%5C%20%5C%5C%20%3D0.01%20)
therefore
the answer part b) is
The ratio of the area of ∆ABC to the area of ∆DEF is
