find the y-intercept of the graph in this equation?
9y+9x=-27
~~~~~~~~~~~~~~~~~~~~~~~~`
To find y-intercept, substitute y=0 into the equation. You will get
9x = -27.
Hence, x =  = -3.
Answer. y-intercept is x = -3.

9y+9x=-27
9y + 9x = - 27
y + x = - 3 ------- Dividing by GCF, 9
y = - x - 3 ------- Subtracting x
It's obvious, from the slope-intercept form of a linear equation (y = mx + b), that b, or intercept = - 3
Thus, y-intercept is at coordinate point: 
OR
Since x is ALWAYS 0 on the y-axis, you could have also just substituted 0 for x and find y. Then you'd get the y-intercept as: (0, y).
