Answer:
The equation of this line would be 4x + y = 13
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we solve the original equation for y.
4x + y - 2 = 0
4x + y = 2
y = -4x + 2
The original slope (the coefficient of x) is -4, which means the new slope will also be -4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line. Just plug in the numbers and solve for the coefficient.
y - y1 = m(x - x1)
y + 3 = -4(x - 4)
y + 3 = -4x + 16
4x + y + 3 = 16
4x + y = 13

Step-by-step explanation:
Given:
The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:

To find:
The selling price if the company wants the weekly revenue to be $1,600.
Solution:
We know that the revenue is the product of quantity and price.



We need to find the value of p when the value of R is $1600.



Divide both sides by 100.

Splitting the middle term, we get



Using zero product property, we get
or 
or 
Therefore, the smaller value of p is $2 and the larger value of p is $8.
