(22,12) m=4
y=mx+b
12=4*22+b
12=88+b
subtract 88 from each side
b=-76
y = 4x-76
subtract 4x from each side
-4x+7 = -76

Answer:
g(f(x)) = 1x² + 1 
Step-by-step explanation:
We are given: 
f(x) = x² - 1 
g(x) = x + 2
And we want to find g(f(x)). 
To do this, we substitute f(x) as x in x+2 (the expression that is equal to g(x)), as g(f(x)) is saying that f(x) is the value of x in g(x). 
So, this will be: 
g(f(x)) = x² - 1 + 2 
Simplify 
g(f(x)) = x² + 1
In your system, place 1 in front of x² - this is the coefficient of x², and also 1 after that - this is a constant.

We want to determine the equation in point slope form for the line that is perpendicular to the given line and passing through the point (5.6) . 
The equation and the point is; 

We know that for two lines to be perpendicular, the product of their slopes should be -1. 
Therefore, the slope of the perpendicular should be; 

The second condition is that the line must pass through the point (5,6) , to do thid, we write the equation of the line in point slope form which is; 

Inserting all values, we have, 

That is the final answer.
