If you meant to write y=23x-4 then none of the lines are perpendicular.

I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.

For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.

So 2/3 becomes -3/2, hence answer D.

The 'inverted' m is called the opposite reciprocal. That's your word of the day.

slope intercept form

y = mx +b

x-y =8

subtract x from each side

-y = -x+8

divide by -1

y = x-8

You need to divide here! Ok so if ten coins weigh twenty five grams, we need to do:

Its easy if its ten you just shift the places. !0 divided by 25 is 2.5
