Answer:
m = -3
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
We use two points
(0,-4) and (-2,2)
m = (2 - -4)/(-2 -0)
= (2+4)/(-2-0)
=6/-2
= -3
Answer:

Step-by-step explanation:
To write the equation of a line with a point and a slope, use the point-slope form of a linear equation. Substitute m = 2/3 and the point (-4,5) into the equation.

Convert to slope intercept form by using the distributive property.

Answer:
12.8$
Step-by-step explanation:
20% is equal to 0.2. You multiply 64 by 0.2. I hope this helps.
I'm not sure about the given data but I plotted the scatter plot based on what I understand on how the data should be presented.
Time (years)
3, 6, 9, 12, 15, 18, 21, 24
Number of participants(x1000)
22, 25, 28, 14, 17, 20,15, 9
Attached is the scatter plot created online.
x = time (years)
y = number of participants
A.) The mean of the 8th and 9th values
