The following lines are 4x + 2y = 8 and y = 2x + 4
parallel
perpendicular
skew
intersecting

Option D.

Step-by-step explanation:

The slope intercept form of a line is

where, m is slope and b is y-intercept.

The given lines are

      ...(i)

       ... (ii)

Rewrite the equation (i) in slope intercept form.

Divide both sides by 2.

      ...(iii)

On comparing equation (iii) with slope intercept form, we get

On comparing equation (ii) with slope intercept form, we get

Since , therefore lines are not parallel.

Since , therefore lines are not perpendicular.

Both lines lies on same plane, i.e., xy-plane, so they are not skew line.

Since both lines lie on same plane and they neither parallel nor perpendicular, therefore they intersecting lines.

Hence, option D is correct.

125 m/min

Step-by-step explanation:

Find the rate (speed) as follows:

 25 meters

= (125/1) meters/min = 125 m/min

(1/5) minute

This is equivalent to about 380 ft/min
