Answer:
y = 2x - 1 Graph B
y = 2x + 2 Graph A
y = 2x - 5 Graph C
Step-by-step explanation:
y = mx + c
c is where the line intersect the Y axis.
<h2>Substitute x for 0:</h2>
y = 2x - 1
2 * 0 - 1 = -1.
This is graph B because it intersects at 0,-1.
y = 2x + 2
2 * 0 + 2 = 2
This is graph A because it intersects at 0,2.
y = 2x - 5
2 * 0 - 5 = -5
This is graph C because it intersects at 0,-5.

Answer: C) There is no positive or negative correlation
A positive correlation is one where the values are increasing, and the line of dots are clearly going down to up.
A negative correlation is the opposite. The values are decreasing, and the line goes from up to down.
This correlation is one that is neither positive or negative. It is a straight line where the values neither increase nor decrease.
