Question

Find a gradient of a line that is parallel and perpendicular to this line with this gradient of -2

Answer 1

a gradient of a line that is parallel and perpendicular to this line with this gradient of -2

Gradient is the slope

So slope of the line =-2

Slope of parallel line is equal to the slope of the line

So slope of parallel line = -2

Slope of perpendicular line is equal to negative reciprocal of slope of the line

We know slope of line = -2

Negative reciprocal =
`(1)/(2)`

So , Slope of perpendicular line=
`(1)/(2)`
