Question

find the slope of each line: y=-2/5x-1 and 4x+10y=10, and determine whether they are parallel, perpendicular, or niether.

Answer 1

Try solving for \(y\) to get the equation in the form \(y=mx + b\).
The slope would be the \(m\) value for both equations.

Answer 2

k thanks

Answer 3

Then, to tell if they're parallel, perpendicular, or neither;
If the slope of equation 1 = equation 2, then they would be parallel lines
If the product of the slopes = -1 (the slope of one is the opposite reciprocal of the other),then the equations are of perpendicular lines.
Otherwise, they're neither parallel nor perpendicular.

You're welcome. :)
