Answer:
y=-3x+5
Step-by-step explanation: y=mx+b
to find slope (m) use the equation 
so
= -3
to find b
use y=mx+b
-1=-3(2)+b
-1=-6+b
5=b
Hope this helps :)

Answer:
length = 24, width = 9
Step-by-step explanation:
Let's call the length and width of the first rectangle w + 15 and w respectively. This means that the length and width of the second rectangle is (w + 15) - 2 and w + 5 respectively. Since the perimeter of the second rectangle is 72, we can write:
2 * ((w + 15) - 2 + w + 5) = 72 because perimeter = 2 * (length + width)
(w + 15) - 2 + w + 5 = 36 (Divide by 2)
2w + 18 = 36 (Combine like terms)
2w = 18 (Subtract 18)
w = 9 (Divide by 2)
This means that the length and width are 24 and 9.
Red apples + green apples = 39 apples
9 red apples + green apples = 39 apples
OR
Red apples = X
Green apples = Y
X + Y = 39
9+Y= 39
Y= 30 (Subtract 9 from both sides)
ratio= 9/30 or 3/10 (reduce the fraction by dividing by 3)
Answer:
Yes
