Answer:
68
Step-by-step explanation:
The formula required to calculate degrees of freedom is given as:
Number of samples - 1
From the above question:
The number of samples = 69
The degrees of freedom is calculated as:
69 - 1
= 68
Answer:
y = -2x - 2
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -2
so now the equation is y = -2x + b
from here, what you could do to find b is...
plug (-2, 2) into the equation
1) x = -2, y = 2
2) 2 = -2(-2) + b
3) 2 = 4 + b
4) -2 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -2)
so "b" would be equal to -2
this makes the final equation y = -2x + (-2) or y = -2x - 2
