Answer:
Step-by-step explanation:
To find the inverse function, the first step we do is change f(x) to Y. So now, we have
y=2x+1
Now that we have this function, we simply flip x and y. When we do that, we get
x=2y+1
Now that we have this function, we just solve for Y. We do that by bring 1 to the other side by subtracting it from both sides, then dividing both sides by 2.
x-1=2y+1-1
x-1=2y
(x-1)/2=2y/2
(x-1)/2=y
So, our inverse function is:
y=(x-1)/2, or y=x/2 - 1/2
Hope I helped!
The standard form of a line:
We have the equation of a line in the slope-point form:
use distributive property
add 3 to both sides
multiply both sides by 2
subtract x from both sides
change the signs
Opposite of 12 is -12
absolute value of -12 is 12
distance between 0 and -12 is 12
absolute value of 12 is 12

Answer:
1/3 is the y intercept
Step-by-step explanation:
f(x) = -2/9x + 1/3
This is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-2/9 is the slope and 1/3 is the y intercept
Answer:
Jonathan's solution 
is correct.
Step-by-step explanation:
Given system of equations are:
Now
The graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And the graph of the linear equation 
cuts the y-axis at the point 
and x-axis at 
And their point of intersection is
And this is Jonathan's solution.
We can see from graph that point of intersection is
