You said that Y = Mx + B
Subtract B from each side: Y - B = Mx
Divide each side by 'x' : (Y - B) / x = M
Four times d to the third minus ten
Slopes of perpendicular lines are NEGATIVE RECIPROCAL to each other
namely, if say one has a slope of a/b then the other will have a slope of
what the dickens does that mean?
well, it means that their product is
so... in this case, one has a slope of 3/4 and the other has a slope of d/2
thus
16 students turned in their homework early i think. I hope this helps
