Answer:

Step-by-step explanation:
We will use the point slope formula: 
We will start by finding the slope(
).
The formula for slope is

So if we just choose 2 random points on the line:
I choose (0,2) and (4,1), we get:

That's our slope.
Next we need to find the y-intercept(
). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.
So in point-slope form the equation is:

Y = 3x - 2.5
You have to get the y by itself.
Subtract 6x to both sides. Then divide by -2.
Um I think it is 2,1 count over 2 then go up1
Answer: 3, it is equal to 2x^2+11x+12
