Answer:
a.(-1,8), (2,9) b. (2,0) (3,5)
Step-by-step explanation:
a.
for (-4, 7) slope is
slope is m=rise /run =rise 1/run3 so to go to the next point
from (-4,7)
rise 1 so now you are at (-4,8) and run 3 and you are at (-1,8)
from (-1,8)
rise 1 to (-1, 9) and run 3 to (2,9)
b
(1,-5) slope is 
from (1,-5) rise 5 to (1,0) and run 1 to (2,0)
from (2,0) rise 5 to (2,5) and run 1 to (3,5)
Answer:
<u><em>The answer would be 17</em></u>
Step-by-step explanation:
You are going to multiply -1 by -5 , that will equal positive 5
So you get 12+5 = 17
X= 2 , y= -3
You have to multiply the second equation by a negative and the you'll get, -3x-y=-3. the y's cancel out and then you combine the x's and the 5 and the 3 and then x=2 and then you pick one of the two equations and sub in the x and solve for y.
Strong correlation: -0.91, 0.82
Medium correlation: -0.49, 0.54
weak correlation: 0.26, -0.18
If the decimal starts with 7,8, or 9 (like .82 or .91), it is strong correlation.
If the decimal starts with 6,5,4 (like .54, .49) then it is moderate correlation.
If the decimal starts with 1,2 or 3 (like .26) then it is weak correlation.
The negative signs have no effect.
