If you mean the slope of the line with equation y = x then it is 1 and there is no y intercept
It is: y = x+3 whereas 1 is the slope and 3 is the y intercept
Set x=0, solve for y, which is the y intercept: 0 - 3y = 9 --> y = -3. Set y=0 and solve for x = 9 for x-intercept.
If: x+y = 9 then y = -x+9 whereas the slope is -1 and the y intercept is 9

y- intercept is positive 9 (+9). x- intercept is between negative 2 and 3 (-2 to -3)
The equation 9=3y has the x-intercept (0,0) and the y-intercept (0,3).

The y intercept will be where the x-coordinate is zero, so set x=0 in the equation and you have: 0 + y = -9, or y = -9. Coordinate (0,-9)
y = mx + b where m is the slope and b is the y-intercept
