The slope between the points (-1,-5) and (r, -9) is 2. What is the value of r?
1 answer:
Answer:
r = 2
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
(-1, -5)
(r, -9)
-5 - (-9) / -1 - r = 2
4 / -1 - r = 2
r = -2
-1 - (-3) = 2
4 / 2 = 2

Answer:
x=3
Step-by-step explanation:
8*3 = 24
4*3=12
24-12=12
5/12 is less than 1/2 because 6/12 = 1/2
Therefore, there are not enough 1/12 pieces to equal or exceed 1/2.
