Answer:
-6/7
Step-by-step explanation:
x2+5x+6=0
7x+6= 0
-6 -6
7x= -6
/7 /7
x= -6/7 or -0.85714285714
The slope is 0 and the y-intercept is (0,18)
Answer:

Step-by-step explanation:
<u>Directly Proportion</u>
It's said that y varies directly proportional as x, if:

Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:

Solving for k:
k=14
Thus, the equation is:
