A. 1) x 2y = 1 and 2x + 4y = 9 (both have a slope of 1/2) 2) A:3 (negative reciprocal) 3) y = x + 5 and y = 8 x (negative reciprocal) 4) Option C: -1/3 (negative reciprocal) Remember, to find the slope of the perpendicular line, take the negative reciprocal of the current line's slope! Hope this helped! ;P

Q. i totally dont get slope!! ugh lol okayy.. write an equation of the line that is parallel to the given line & passes through the given point. 1)). y=3x-1 , (0,2) 2.) y=x+3 , (1,2) 3.) y= -3x+5 , (-1,4) 4.) y=5x+2 , (3,2) 3.) y= -2x -1 , (2,6) 4.) y=2/3x+5 , (1,1) 5.) 2y=6x-4 , (0,3) 6.) 3y=x+5 , (6,0) 7.) 2x-4y=8 , (-3,1) word problems!! ugh ha 1. between 1990 and 200, the monthly rent for a one bedroom apartment increased by $27 per yr. In 1997, the rent was $375 per month. a.) Find an equation that gives the monthly rent in dollars,Y, in terms of the year,T. Let T =0 correspond to 1990. b.) determine the rent for 1999. 2. Between 1992 and 1999, you addded 21 stamps per year to your collection.In 1997 you had 109… [cont.]

A. I think you wrote the first part wrong, you can't have two parallel lines that go through the same point. Word Problem The question doesn't make sense again. The problem self-contradicts itself. The rent couldn't be only $375 after 7 years.
