2x+y=3 is a line that has a -2 slope and 6x=9-3x is a vertical line. They will cross at one place. That is (1,2)
That line is [ y = 2 cos(2x) ].
It is: y = -1/2x-8
-2
It is: -1/2x or as a decimal -0.5x

The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
No they are parallel.
That line is [ y = 2 cos(2x) ].
It is: y = -1/2x-8

It equals to the equation of a straight line.
For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )
