Question

I WILL GIVE BRAINLIEST TO FASTEST ANSWER!!!! I KNOW I ALREADY POSTED THIS BUT PLEASE HELP ASAP!!!!!!!!!

Answer 1

17. y = -2/3x + 2
    2/3x + y = 2
    2x + 3y = 6 <==

18. y = 3x + 7....slope is 3. A parallel line will have the same slope.

y = mx + b
slope(m) = 3
(2,10)...x = 2 and y = 10
now sub and find b, the y int
10 = 3(2) + b
10 = 6 + b
10 - 6 = b
4 = b
so ur equation is : y = 3x + 4 <===

19. - 5x + 10y = 5                
      10y = 5x + 5
       y = 1/2x + 1/2...slope is 1/2
   
      y = -2x + 4....slope is -2

1/2 and -2 are negative reciprocals of each other....so ur lines are perpendicular

20. y = -1/4x + 8....slope is -1/4
  
     -2x + 8y = 4
      8y = 2x + 4
      y = 1/4x + 1/2...slope here is 1/4

different slope and different y intercepts ...neither parallel or perpendicular

21. slope in the equation is 8/3. A perpendicular line will have a slope of -3/8.

y - y1 = m(x - x1)
slope(m) = -3/8
(-2,3)...x1 = -2 and y1 = 3
now we sub
y - 3 = -3/8(x - (-2) =
y - 3 = -3/8(x + 2) <==
