nydimaria [60]
4900=4200(1+r/2)^(2*4)
Solve for r
R=(4900/4200)^(1/8))-1)*2
R=((4,900÷4,200)^(1÷8)−1)×2
R=0.039*100=3.9%

What is the equation of the graphed line in point-slope form?
SSSSS [86.1K]
First, we find the slope
(4,0)(0,-3)
slope = (-3 - 0) / (0 - 4) = -3/-4 = 3/4

there can be 3 possible answers for this..
y - y1 = m(x - x1)
slope(m) = 3/4
using points (4,0)...x1 = 4 and y1 = 0
now we sub
y - 0 = 3/4(x - 4) <== this is one answer

y - y1 = m(x - x1)
slope(m) = 3/4
using points (0,-3)...x1 = 0 and y1 = -3
now we sub
y - (-3) = 3/4(x - 0) =
y + 3 = 3/4(x - 0) <== here is another answer

y - y1 = m(x - x1)
slope(m) = 3/4
using points (-4,-6)...x1 = -4 and y1 = -6
now we sub
y - (-6) = 3/4(x - (-4) =
y + 6 = 3/4(x + 4) <=== and here is another answer

What kind of association is this, negative or positive?​
erik [133]

Answer:

negative association

Step-by-step explanation:

This diagram is a scatter plot which represents a set of data.  Data on a scatter plot can fit one of three descriptions:  positive (increasing), negative (decreasing) or no association (points do not form any kind of line).  Given this data and the line of best fit, or the line that pass through the majority of the points, it is a decreasing line.  Since the line goes downhill, it is a negative association.
