@cwrw238  can you please help?

anonymous · Answer

the first problem represent equations of the same exact line so there are infinitely many solutions

anonymous · Answer

Parallel lines have the same slope; perpendicular lines have the opposite inverse slope (-4 and 1/4 are perpendicular). 
The 2nd problem: one line has a slope of -2/3 the other has a slope of 2/3.  What should the answer be?

anonymous · Answer

39. y+2 = 1/3(x-5)   (-4,3)
      y + 2 - 2 = 1/3x - 5/3 - 2
      y = 1/3x -5/3-6/3
      y = 1/3x - 11/3    Here's the given line. The slope is 1/3. What will a perpendicular line slope be?

-3?

anonymous · Answer

yes.. so the equation is y-y1 = -3(x-x1)   (-4,3)
                                   y-3 = -3(x+4)
                                   y-3 = -3x-12
                                   y = -3x -9
