If the equation of a line is [ Y = -2 ] the the line is horizontal. Its slope is zero.
The slope of the line y = -2 is zero.
Slope is 2.
Slope = 2
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 )
y = 0.25x + 2 The slope of the line is 0.25
The slope is -4
The slope is 5.
the slope is - 2 and the y intercept is 4
y = 2/3x - 2
