Answer:
<h2>
         y = -¹/₂x + 5</h2>
Step-by-step explanation:
The product of slopes of perpendicular lines is -1
y = 2x − 4  ⇒   m₁ = 2
m₁m₂ = -1
2m₂ = -1
 m₂ = -¹/₂
The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)
m = -¹/₂
(4, 3)  ⇒  x₁ = 4,  y₁ = 3
So the equation in point-slope form:
                                                   y - 3 = -¹/₂(x - 4)
Therefore:
y - 3 = -¹/₂x + 2
y = -¹/₂x + 2 + 3
<h3>
y = -¹/₂x + 5</h3>
 
        
             
        
        
        
i can give you the exact answer to your question, but what are the equations for the companies and  how much do the edwards have to spend? if not, here's how to do it:
y= m(225)+b for each company. i used slope-intercept form assuming that's what form the equations are written in. it's basically saying x=225 in part a (look for the lowest y) and in part b y≥m(225)+b (look for which company's equation makes the statement true)
(ps i'm checking every few minutes if you want to comment and get the exact answer)
 
        
             
        
        
        
We are given 

Firstly, we simplify left side
Left side is 

we will make all x terms together 
and y terms together



we can multiply left side by using exponent rule 



now, we can set them equal 

Since, both sides have x,y and 8 
and both are equal 
so, their exponent must be equal 
so, exponent of y must also be equal 
we get

Answer:
diameter = IJ
radius = KH or IH or JH
chord = LM
length HK = 2
Step-by-step explanation:
if IJ is the diameter and the radius is KH then r must be 2 as the radius is always half the diameter
