Answer:
y- intercept = - 2.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m =  =
 =  = - 4.5 , then
 = - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5 
 
        
             
        
        
        
Based on the graph, the total perimeter of the doghouse Jeremy plans to build s 28 feet (twenty-eight feet).
<h3>What is the perimeter?</h3>
This is the total distance of all the sides in a shape. Due to this, the general formula is:
- Perimeter = side + side + side.
<h3>What is the perimeter of the doghouse?</h3>
- Horizontal side: 8 feet
- Vertical sides: 10 feet
- Diagonal sides: 10 feet
8+10+10= 28 feet.
Note: This question is incomplete because the graph is missing; here is the graph:

You probably are interested in expressing the given equation as a quadratic equation in u, as it will make it easy to find the solutions.
Let u = x²
So,
u² = x⁴
So, the given equation can be written as:
u² - 17u + 16 = 0
Now the equation is quadratic in u and the solutions can be calculated using quadratic formula or factorization.
