Question 814933: find the slope of each line.
y = 2x -3
2y = -x + 4
In each pair of equations give the slope and then determine whether the two lines are parallel, perpendicular, or neither.
1)2x + 5y =4
4x + 10y = 1
2) 5x - 3y = -2
3x- 5y = -8
Write an equation of the line passing through each pair of points. Give answer in slope-intercept form, if possible.
1) (2,7),m = 3
2)(-1,-7) and (-8,-2)

Hi,

find the slope of each line.

y+=+highlight++%282%29x+-3

 2y = -x + 4  0r  y+=+highlight+%28-1%2F2%29x%2B2}

 In each pair of equations give the slope and then determine whether the two lines are parallel, perpendicular, or neither.

 1)2x + 5y =4  0r  y+=+highlight+%28-2%2F5%29x+%2B+4%2F5

 4x + 10y + 1  0r  y+=+highlight+%28-2%2F5%29x+-+1%2F10

 2) 5x - 3y = -2  0r y+=+highlight+%285%2F3%29x+%2B+2%2F3

 3x- 5y = -8   0r  y+=+highlight+%283%2F5%29x+%2B+8%2F5 

 Write an equation of the line passing through each pair of points. Give answer in slope-intercept form, if possible.

 1) (2,7),m = 3  (y-7)= 3(x-2)  0r  y+=highlight+%283%29x+%2B1  

 2)(-1,-7) and 

   (-8,-2)  m = %28-7-%28-2%29%29%2F%28-1-%28-8%29%29+=+-5%2F7

  y-7 = (-5/7)(x-2)  0r y+=highlight+%28-5%2F7%29x+%2B+49%2F7+%2B+10%2F7
