Answer:
The slope of the line 
is 
Step-by-step explanation:
The given equation can be written as
represents a line equation.
The general equation of the straight line is 
where m is the slope and c is intercept
Comparing equations (1) and (2) we get slope 
Therefore slope of the line is
Answer:
a)3
b) 9
c) -3
Step-by-step explanation:
a) If B is obtained by adding a multiple of a row of A to another row of A, 
Then, 
.
b) If B is obtained by multiplying a row of A by k, then 
. Then 
c) If B is obtained by exchanging two rows (columns) of A, then 
. Then 
Year Sam Sally1: X (3/2)X-10002: (5/2)X-2000 2X-15003: X/5+1000 X/4+1400Total 37X/10-1000 15X/4-1100
Since their investments are known to be equal, we equate the two totals and solve for X.37X/10-1000=15X/4-1100(150-148)X/40 = 1100-1000X/20=100X=2000
So Sam invested $2000 the first year.Sally invested X/4+1400=1900 in the last year.
Let w represent the amount the wife receives.
.. w +2*(2/3*w) = 945,000
.. 7/3w = 945,000
.. w = (3/7)*945,000 = 405,000
The wife will receive $405,000.
