Answer:
The answer is: y = 7
Step-by-step explanation:
For x = 4, it is a vertical line where everything is x = 4. No matter what y is, x always equals 4.
For the line y = 7, it is a horizontal line, perpendicular to the line x = 4. The line y = 7 passes through the point (-1, 7) and all other similar points where y = 7.

Let x represent pounds of Gazebo coffee and y represent pounds of Kona coffee.
We are told that a coffee distributor wants 70 pounds of coffee. We can represent this information in an equation as:
We have been given that Gazebo coffee blend sells for $10.20 per pound, so cost of x pounds of Gazebo coffee would be .
Kona coffee blend sells for $12.20 per pound, so cost of y pounds of Kona coffee would be .
Cost of 70 pounds of a coffee that can sell for $10.91 per pound would be .
Upon substituting equation (1) in equation (2), we will get:
Therefore, distributor should use 45.15 pounds of Gazebo coffee.
Upon substituting in equation (1), we will get:
Therefore, distributor should use 24.85 pounds of Kona coffee.
