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 )

Q: What is the slope of a line that is perpendicular to the line whose equation is 2x plus y equals 8?

the slope will be positive 1.5x the whole equation is y=4.5+1.5x

- 1/3

It is -1/2

Without an equality sign it can't be considered to be an equation but in general if the slope was 3 then the perpendicular would be -1/3

20x+12y = 2012 12y = -20x+2012 y = -5/3x+503/3 Therefore the perpendicular slope is the positive reciprocal -5/3 which is 3/5

3x+y = 4 y = -3x+4 Perpendicular slope: 1/3

4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3

If you mean y = 2x+5 then the perpendicular slope is -1/2

Get the slope of the given line, by putting it into slope-intercept form. Then you can divide minus one by this slope, to get the slope of any perpendicular line.
