Answer:
x + 3
Step-by-step explanation:
Recall that the y-intercept is when the function passes the y-axis. This happens when x=0. Therefore, we can find our y-intercept by plugging x=0 into our function and solving for y.
6x + 9y = 18
6(0) + 9y = 18
0 + 9y = 18
9y = 18
y =2
Thus, our y-intercept is when x = 0 and y = 2, or (0,2).
Sorry sorry I need to answer a question to ask one
we have given an equation 
we need to simplify the given equation.
the distributive property is used here 

if we simplify the terms
we get
.
X-6x=56
-5x=56/:(-5)
x=-56/5
x=-11 1/5
