2y+8x=21
This is in standard form, lets convert to slope intercept form

slope intercept form : y = mx + b

2y + 8x = 21
      -8x      -8x

2y = -8x + 21
y = -4x + 21/2

Answer: m = -4

       8x + 2y = 21
8x - 8x + 2y = -8x + 21
               2y = -8x + 21
                2           2
                 y = -4x + 10.5

Slope: -4
