Question

Determine whether the graphs of the given equations are parallel, perpendicular, or neither

Answer 1

Answer:

C. Neither

Step-by-step explanation:

The first equation is $y=2x+13$

This equation is already in the slope-intercept form; $y=mx+c$

The slope of this equation is 2.

The second equation is $y=-2x+2$.

This equation is also already in the slope-intercept form.

The slope of this equation is $-2$.

Since the two slopes are not the same, the two lines are not parallel.

If these two lines are perpendicular, then the product of their slopes is -1.

But $2\times -2=-4$ which is not equal to -1.

Therefore the two lines are also not perpendicular.

The correct choice is C.

Answer 2
