Answer:
A correlation exists in a scatter plot if there is a general trend in the outputs as inputs increase. If the outputs generally increase in value, then there is a positive correlation. If the outputs generally decrease in value, then there is a negative correlation.
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5

Answer:
<h2>y = -3x - 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
We have two points (1, -4) and (-2, 5).
Substitute:
Substitute the value of a slope and the coordinates of the point (1, -4) to the equation of a line:
<em>add 3 to both sides</em>
Finally:
