The slope point form is

m is the slope
x1, y1 are the coordinates of a point on the line
The slope of the line is -1
m = -1
point (-5, -4) lies on the line
x1 = -5 and y1 = -4
Let us substitute them in the form above

Remember (-)(-) = (+)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)
The candle sales decreases to - 15 percentage.
<u>Step-by-step explanation:</u>
(476 - 560) : 560 x 100
= (476 : 560 - 1)100
= 85 - 100 = - 15
Therefore, - 15% did the candle sales decrease.
Answer:
Assuming it would be -x-4
Answer:
m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.
Step-by-step explanation:
To determine all values of m so that the function y= e^mx is a solution of the given differential equation.
First, we will find y'.
From, y= e^mx

But, 
Hence,

∴ 
Now, we will put the values of y' and y into the given differential equation y' + 2y =0
From the question,

and

Then,
becomes

Then, 

∴
Hence, m = - 2 is the value of m that the function y= e^mx is a solution of the differential equation, y' + 2y = 0.
