Question 240811: I'm having problems with writing an equation of a line that is perpendicular because our text book doesn't do a good job explaining it.
"write the equation of a line that is perpendicular to the given line and that passes through the given point." -4x-8y=24; (4,-1) the opions they give you are
1.) y=2x-9
2.) y=1/2x+6
3.) y=1/2x-9
4.) y=-2x-9
I found the negative reciprocal of 4 which is -1/4 and that's as far as I have gotten. After 13 hours of doing this homework I honestly can't understand what I'm reading.

Question 241225: when doing systems of equations and graphing, i have a problem that reads
4x - 20 = 5y
8x - 10y = 12
i know how to graph the first equation but how do i graph the second equation? i was told by my instructor to solve using the intercept points by substuting the exponent with zero (4 * 0) - 20 = 5y and solve then sub zero for the other exponent and then graph the line but with the second equation the numbers come out in fraction form and i can not figure out how to graph the intercepts. any and all help would be appreciated...
thanks...

Question 241575: A pelican flying in the air over water drops a crab from a height of 30 feet. The distance the crab is from the water as it falls can be represented by the function h(t)=-16t2+30, where t is time, in seconds. To catch the crab as it falls, a gull flies along a path represented by the function g(t)=-8+15. Can the gull catch the crab before the crab hits the water? justify your answer. If so, find the time it is caught and the distance above the water at that time.
