Answer:
A. Undefined slope (no slope)
B. 
Step-by-step explanation:
A slope is rise over run.
The points (6, 2) and (6, -3) are located on the same x coordinate, therefore they have an undefined slope.
However, the points (-4, -7) and (4, 3) do have a slope. The rise is 10 ( | -7+ 3 | ) and the run is 8 ( | -4 + 4 | ). 10/8 is equivalent to 5/4.

Since the number of children in a group (c) is multiplied by 16.30 in the model, we can say that the total amount of purchase (d) will increase by a value of $16.30 for each additional child that will be added to the group. Examining the choices, we find one that is similar to this explanation:
ANSWER: A. The model predicts that for each additional child in a group, the total amount of purchase increases by $16.30.
Answer:
e
Step-by-step explanation:
let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.
x + y = 12 ( subtract y from both sides )
x = 12 - y → (1)
360x + 450y = 4950 → (2)
substitute x = 12 - y into (2)
360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side
4320 - 360y + 450y = 4950
4320 + 90y = 4950 ( subtract 4320 from both sides )
90y = 630 ( divide both sides by 90 )
y = 7
there are 7 two- bedroom apartments
Simple subtraction. to find how many robin has, subtract 9 from 23, which is 14. so robin has 14 comic books. robin has 5 more than lee, so subtract 5 from 14, which is 9. so lee has 9 comic books
Y = 7x - 48
use slope formula so, y2 - y1 over x2 - x1 to get your m value or your slope which is 7. then plug in the slope and a random set of point so I used (6, -6). -6 = 6(7) + b, simplify.
-6 = 42 + b, subtract 42 which leaves you with b= -48. hope this helps :)
