Question

Y=4x-2 and y=-4+1 is.perpinducular or.not?

Answer 1

No

Explanation:

These are written in slope-intercept form:

`y=mx+b`

m is the slope and b is the y-intercept

When two lines are perpendicular, their slopes will be opposite reciprocals of each other. For example:

`y=-2x+5\\\\y=(1)/(2)x-9`

The lines above are perpendicular because the slopes:

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

are opposite reciprocals.

In the given lines, the slopes are not opposite reciprocals:

`m=4\\\\m=-4`

So they are NOT perpendicular lines.
