find the slope of each line 9x+2y=-8 and y=0 thanks who can help me

wright the slope-intercept from of the equation of each line x-y=-7 and x-2y=-2
y=0 is the same as y = 0x+0
so, its slope is zero.
9x+2y = -8 is the same as
2y = -9x - 8
y = -9/2 x - 4
so its slope is -9/2
Try the others. Rearrange stuff to get y all alone on the left side, as I did above.
so, its slope is zero.
9x+2y = -8 is the same as
