Answer:
slope = 7 and point = (3, 7)
b = y - slope*x
b = 7 -7 * 3
b = -14
Then we enter "b" and the slope into this equation:
y = 7x -14
Step-by-step explanation:
 
        
             
        
        
        
The answer is D because and obtuse angle is 91 degrees or more
        
                    
             
        
        
        
Answer:
(assuming you are knowledge about Pythagoras theorem)
44.205
Step-by-step explanation:
draw the altitude line to the upper right corner and the lower left corner and you have 2 identical right triangles and a rectangle. If you solve the third side of the right triangles you get 1.685 (sqrt[7.2^2 - 7^2]).
now add up the areas of both triangles and the rectangle in the center whose base is 4.63 (subtract the 3rd side from 8)
you have 
1.685(7) + 7(4.63)
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Hi there! I'm glad I was able to help you solve this equation!
Let's start by simplifying both sides of the equation. It's easier to solve it this way!

Distribute:


Combine 'like' terms:


Next, you'll want to add 36 to both sides of the equation.


Finally, divide both sides by  .

Answer:
y = 3x - 8
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
4 - 1 / 4 - 3 = 3/1 = 3
m = 3
b = y-intercept
b = -8
y = mx + b 
y = 3x + (-8)
y = 3x - 8
