Answer:
(-10, 3)
Step-by-step explanation:
You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.
Step 1: Rewrite 2nd equation
2y = 6
y = 3
Step 2: Plug in <em>y</em>
7x + 8(3) = -46
7x + 24 = -46
7x = -70
x = -10
Put it in coordinates and we have our final answer!

So basically the hypotenuse is the part of the triangle that connects the two sides that create the right angle
        
                    
             
        
        
        
The ordered pairs would be (x-2, -y).
Translating a graph to the right subtracts the number of units from the x-coordinate.
Reflecting across the x-axis negates the y-coordinate.
        
             
        
        
        
Answer: y = x-2
y = 3x + 5
x-2 = 3x+5
x+3x = 5+2
4x = 7
x = 7/4
y = x-2
y = 7/4 - 2
y = 7-8/4
y = -1/4
