Question

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.explain how you knew this.

Y=-1/4x+9
32x-8y=-8

Answer 1

Hey there!

First let's look at our equations.

Y= -1/4x+9 This looks like it can go in a graphing calculator just as it is.

32x-8y=-8 For this equation, we have to determine the value of Y.

32x-8y=-8

-32x-8y= -8-32x

-8y=-32x-8

+8 +8

y=-32x

Now put these equations in a calculator, and you'll see these lines are Perpendicular.

I hope this helps!
