Answer:
y=x+1 :)
step by step explanation:
Hey there!
We'll be writing them in slope-intercept form. Slope intercept form is defined as:
y = mx + b
With m being the slope and b as the y-intercept. Now, we can just plug them in.
1)
y = -3x - 2
Slope = -3
Y intercept = -2
2) y = 5x + 7
Slope = 5
Y intercept = 7
3) y = -3/4x + 3
Slope = -3/4
Y intercept = 3
4) y = 5/2x - 6
Intercept = -6
Slope = -5/2
Hope this helps!
What I gather from the question is that
has second moment
and variance
, and you're asked to find the expectation and variance of the random variable
.
From the given second moment and variance, we find the expectation of
:

Expectation is linear, so

Using the same variance identity, we have

and

so that

Alternatively, we can use the identity

Y=1/2x+1.5
hope that helps!
