Answer:
Y= 3/2x-12
Step-by-step explanation:
perpendicular is the opposite slope and just put the 4 in for x
Answer:
See below
Step-by-step explanation:
a. here you are to multiply the two functions together:

b. here you are to subtract g from f:

c. here you are to compose g into f. In other words, pick up the whole g function and plug it into f wherever you see an x:

d. here you are compose f into g. In other words, pick up the whole f function and plug it into g wherever you see an x:

You now have to FOIL out the (3x-1) like so:
![2[(3x-1)(3x-1)]](https://tex.z-dn.net/?f=2%5B%283x-1%29%283x-1%29%5D)
which gives you

Distribute in the 2 and you'll end up with the answer:

Step-by-step explanation:
it is the ratio of y change / x change.
when we look at the points with integer coordinates, we see that whenever x increases by 1 unit, y increases by 2 units.
so, the gradient is
+2/+1 = 2/1 = 2
