the slope will be positive 1.5x the whole equation is y=4.5+1.5x
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 )
x = -3 represents a vertical line whose slope is undefined.

the slope will be positive 1.5x the whole equation is y=4.5+1.5x
3x+y = 4 y = -3x+4 Perpendicular slope: 1/3
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 )
4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3
x = -3 represents a vertical line whose slope is undefined.
Rearranging the original equation, we get y=-(2/3)x+12. Since 12 is the constant, this is the point that the line of this equation will cut the y-axis if x=0. Therefore, -(2/3) is the gradient and for an equation to produce a parallel line, the gradient must be equal. Summing up, y=-(2/3)+c (where c equals any real number) would be parallel
