Answer:
The value of a = 3
Step-by-step explanation:
Given the function
From the attached graph, it is clear that
at x = 0,
∵ 
Thus
When x = 0, the y-intercept will be:
From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation
3 = a ∵ 
Therefore, the value of a = 3
Answer:
-3
Step-by-step explanation:
1. Plug in -2 for y, because it is the y value in the coordinates
2. Simplify -2 = -2x + 4(-2)
3.That simplifies to -2 = -2x - 8
4. Add 8 to both sides to get 6 = -2x
5. Divide both sides by -2
6. x = -3
Answer: moderate positive correlation
Step-by-step explanation: If your correlation coefficient is positive, that means that your slope which is how steep the line is or your line of best fit must also be positive.
Remember that the correlation coefficient is just a number that indicates the direction and closeness of points of a line of best fit.
If it has a correlation coefficient of 0.89, the points would be close together but not very very close.
