MATH HELP PLEASE! PLEASE?
1.) The slope of the line PQ is (-2/3) find the slope of the line which is parallel to PQ
2.)Line DR passes throught F (-2,3), and is perpendicular to the line described by the equatino y=2x +1. Find the equation for the line DR>
3.) Line PQ passes throught R (3,-4), and sloope is -3. Find the equatino for the line PQ.

Dude u suck! Pay attention in Class!
1)Lines that are parellel have THE SAME SLOPE!!!!
2) Lines that are perpendicular have THE NEGATIVE RECIPROCAL slope. example slope 1/2 .. line perpendicular is -2/1 =-2
3) Use the point that give u an the slope! and plug values into the equation y = mx +b. You solve for b!!! then plug into final equation
Pay attention in class... u cant expect ppl on yahoo answers to just give u the answers! learn how its done!!!

There you go, you included the slope for the last one:
y+4=1/3(x-3)
y+4=1/3x-1
y=1/3x-5
y+4=1/3(x-3)
y+4=1/3x-1
y=1/3x-5

Yuck!
