-5

It is: -1/2

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

- 1/3

It is -1/2

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.

y = 0That's the equation of the x-axis.Its slope is zero.

x - 4y = 3 is the slope of a line perpendicular to line whose equation is y -5 3x plus 8 3.

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

The slope would be 3/4

Slope of a line = m slope of perpendicular line = -1/m

2/3.

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

-5/3

1.67 or 1.667

The slope is 5. Parallel lines always have the same slope.

x = -3 represents a vertical line whose slope is undefined.

1) Solve the given equation for "y". The resulting equation will be in slope-intercept form, so you can immediately read off its slope. 2) Any line parallel to that line will have the same slope.
