Answer:
22
Step-by-step explanation:
If you mean to put it into y=mx+b, then simply input m and b into that formula.
So it would be y=1/2x-4
Answer:
C. Positive Correlation
Step-by-Step explanation
Because a positive correlation is a relationship between two variables that move in tandem—that is, in the same direction.
The value of k in <span>
1/2 k+6=4k-8</span>
is 4
Answer:
line FG
Step-by-step Explanation:
In the diagram, line CD passes through
The slope of this line is found using the formula,
We substitute the values to get,
So line CD is the line with slope
From the graph we can see clearly that, the only line that is perpendicular to CD is line FG.
Line FG also passes through
We can verify that the product of these two slopes is negative 1.
Therefore the correct answer is C
