It is 9.
y- intercept is positive 9 (+9). x- intercept is between negative 2 and 3 (-2 to -3)
If: x+y = 9 then y = -x+9 whereas the slope is -1 and the y intercept is 9
At the x-intercept, y = 0 So the equation becomes 4x = -36 or x = -9 So the x-intercept is (-9, 0)
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.
The equation 9=3y has the x-intercept (0,0) and the y-intercept (0,3).
(x + 6y)(x - 3y)
-3
