Answer:
Step-by-step explanation:
In this particular case we have the following system of equations:
y
=
−
3
x
+
4
[
E
q
.
1
]
x
+
4
y
=

6
[
E
q
.
2
]
Substituting
[
E
q
.
1
]
in
[
E
q
.
2
]
:
x
+
4
(
−
3
x
+

)
=

6
Applying the distributive property on the left side:
x
−
12
x
+
16
=

6
Simplifying
:
−
11
x
=
−
22
Solving for
y
:
x
=
−
22
−
11
=
2
Substituting
x
=
2
in
[
E

:
y

Therefore
, the solutions are
x

and
y

Answer:
Mean absolute deviation is the average of the absolute deviations from the mean. It is a measure of variability, which gives us an idea about the spread of data points from mean. Therefore, the small MAD means the data points are less deviated from mean. And the large MAD means the data points are more deviated from mean.
Hence, smaller the MAD lesser the variation in data.

Answer:
m = 4.08
Step-by-step explanation:
The line that fits good for the given data is given by :
y = 4.08x + 63.13
We need to find the slope of the given line.
The general equation of the line is given by :
y = mx +c
Where
m is slope of the line
c is y-intercept
So, the slope of the given line is 4.08.
