Correct Question :
Find the range of the values of x and y for which the following holds true :
2x + y ≥ 4
Solution :
The positive side [ The portion on right ] of the line with the equation , y - 2x + 4 = 0
Explaination :
The graph of the inequation is shown in the attachment .
The red zone bounds the region of the Cartesian coordinate planes where the inequality holds true .
We have found two integral values of x and y satisfying 2x + y ≥ 4 lying on the bounding line .
These are :
• x = 2 and y = 0
• x = 0 and y = 4
Let us find the equation of the line passing through these two points .
Slope of line ,
m = ( y2 - y1)/( X2 - X1)
=> [ 4 ]/[ -2 ]
=> -2
By the slope form equation of a line :
y - y1 = m ( x - X1)
=> y = -2( x - 2)
=> y - 2x + 4 = 0
This is the required equation of the line bounding the field of solution .
