Question

Which equation is perpendicular to y= 1/2x + 4

Answer 1

The equation is given as

`y=(1)/(2)x+4`

For finding the perpendicular line,

The product of slope is -1.

For the given equation , the slope is 1/2.

Now find the slope of perpendicular line.

`(1)/(2)* m=-1`
`m=-2`

Hence the slope of perpendicular line is -2.

Now the perpendicular equation to the given line can be

y=-2x+b.

Where assume b=1.

Then the equation perpendicular to the given line is

`y=-2x+1`
