Hello!
First of all we find the slope by dividing the difference of the y values by the difference of the x values as seen below.

The slope of our line is 7/2, or 3.5
-------------------------------------------------------------
Now we will put the slope and a point on our line into slope intercept form and solve for b. We will use (-3,11).
11=3.5(-3)+b
11=10.5+b
b=0.5
Our final equation is shown below.
y=3.5x+0.5
I hope this helps!
Answer:
(1,0)
Step-by-step explanation:
we can't factor this so we'll use the quadratic formula

(use both of them because usually there are two zeroes)
We have

Therefore the x intercept is just (1,0)
Answer:
The slope is -6 and the y intercept is 0
The value of (f-g)(144) is 0
Step-by-step explanation:
We are given:

We need to find value of (f-g)(144)
We will put x=144 for both f(x) and g(x)

So, the value of (f-g)(144) is 0
