180n-360=150n\implies 30n=360\implies n=\cfrac{360}{30}\implies n=12

Determine which system of equation has (-3,19) and (4,-23) as a solution?
grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

\frac{4--3}{-23-19} which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1
