16. tell whether the lines for each pair of equations are parallel, perpendicular, or neither. y= -1/4 x + 8-2x + 8y = 4

Given equation are:

                 ......[1]

                            .....[2]

Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.

Slope of equation of line in [1] is;

then;

Slope of equation of line in [2];

Add both sides 2x we get;

-2x + 8y + 2x = 2x + 4

Simplify:

8y = 2x +4

Divide both sides by 8 we get;

then;

Therefore, the given two lines are neither parallel nor perpendicular.
