Guided Practice Directions: Describe each pair of ratio. Write P if it is a proportion and NP if
not proportion.
1.) 4:6 = 20:24
2.) 9: 6 = 36:24
3.) 2:5 = 15:45
4.) 3:5 = 6:10
5.) 40: 16 = 5:2​

1) NP

2) P

3) NP

4) P

5) P

Step-by-step explanation:

re-write all the pairs into fractions

1.)     {4 x 5 = 20}  and {6 x 4 = 24}     5 ≠ 4  

I can do an explanation for each one if you need; just comment, cause I'll be on here for a while.  Good luck! :D

.

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
