2x - 9y = - 5
2x - 9y - 2x = - 2x - 5
- 9y = - 2x - 5
- 9y / - 9 = - 2x / - 9 - 5 / - 9
y = - 2x / - 9 - 5 / - 9
y = 2/9x + 5/9

2x-9y=-5
change it to y-intercept form: y = mx+b, where m is the slope
-9y=-2x-5
divide the equation by 9 (value of y)
-y=-(2/9)x-(5/9)
multiply by -1 (so that y will have a positive value)
[-y=-(2/9)x-(5/9)]-1
then...
y=(2/9)x+(5/9)
so... m = 2/9... slope is 2/9

2x -9y = -5
9y = 2x +5
y = (2/9)x + (5/9)
slope is 2/9

2x – 9y = –5
2x/9 -5/9 = y
slope is 2/9

y=mx+b
-9y=-2x-5
-9y/-9=-2x/-9+5/9
y=2x/9+5/9
slope is 2/9
