Answer:
<h2>
</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
First of all to find the equation of the line we must first find the slope.
The slope of the line using points
(0,-2) (8,-4) is
<h3>
</h3>
Now using one of the points and the slope we can find the equation of the line.
Equation of the line using point (0 , - 2) and slope - 1/4 is
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
Answer:
Required value of k is 43% .
Explanation:
Lets assume original regular price of sports jacket = x
On sale , price of jacket is reuced by 30%
Sales price = x - 30% 0f x
Sales price= x – 0.30x
Sales price= 0.70x
Once sales is over price of jacket is increased by k%
That is
Sales price + k% of Sales price
= 0.70x + k% 0.70x
Also given after increasing to k% , price becomes equal to regular price
=> 0.70x + k% of 0.70x = original regular price
=>
=>
=>
=> 0.70k = 100 x 0.30
=>that is 43
Hence required value of k is 43% .

= 49/6
= 8 1/6
EDIT: I copied the problem wrong
Line thru (-3,-5) and (6,1) in standard form.
Point point form for the line joining (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
(6 - -3)(y - -5) = (1 - -5)(x - - 3)
9(y + 5) = 6(x + 3)
9y + 45 = 6x + 18
27 = 6x - 9y
2x - 3y = 9
Ax + By = C
That satisfies the constraints,
A=2, B=-3, C=9
A+B+C=8
Answer: 8
Check: 2x - 3y = 9 thru (-3,-5) and (6,1)
2(-3)-3(-5)= -6 + 15 = 9 good
2(6) - 3(1) =12 - 3 = 9, good
