Answer:
y=-3/4x-3
Step-by-step explanation:
y=mx+b
find the y intercept=b
y=mx-3
find the slope
y=-3/4x-3
18) Value of b is : 
Option A is correct.
19) Option C is correct.
Step-by-step explanation:
18) We need to find the value of b.
The given equation is:

Solving to find the value of b:

So value of b is : 
Option A is correct.
19) We need to find the correct graph of the equation:

Solving:

The values of y will be less than three. As y < 3 so, the circle on y is not filled.
So. Option C is correct.
