The slope is 3
whatever is in front of the x is the slope
have joint density
We can find 
by integrating the joint density over the region in 
where 
in the first quadrant, i.e. above the line 
:
using the fact that
Then using the same property,
X=7. Undefined
X=-7. Undefined
Answer:
y = 1/2x +2
Step-by-step explanation:
y-y1= m (x-x1)
first find slope
m= 4-1 / 4 - (-2)
m= 3 / 4+2
m= 3/ 6
m = 1/2
you can pick any of the two points to solve for point slope form
y-4 = 1/2 (x-4)
y-4= 1/2x -2
add 4 on both sides
y = 1/2x +2
y-1= 1/2 (x- (-2))
y-1= 1/2 (x+2)
y-1= 1/2x +1
add 1 on both sides
y= 1/2x +2
you should get the same answer with any of the two points you chose
you might want to use a calculator to solve this
if you want to use both points to make sure the answer is correct, you can
if you don't get the same answer with both points then u did something wrong during the equation.
I'm not sure I think the answer is 2.433 and 6.848) and 737383) but I'm not sure
