an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
2x-y=12
-y=12-2x
(-y=12-2x)devide -1
y = -12+2x
y=2x-12
ANSWER = C
Answer:
1/10
Step-by-step explanation:
1/2 divided by 5 = 1/10
slope=(-16-5)/(-8-18)=21/26
Answer:
Use points (4,1) and (3,-1)
Step-by-step explanation:
Let's say the other coordinates are (x,y).
Then, we know (1-y)/(4-x)=2. So if y is -1, and x is 3, then we get:
[1-(-1)]/(4-3)=2/1=2
So draw the two points, (4,1) and (3,-1) on a coordinate plane, and use a ruler to make a line that goes through both the points.
