Answer:
Third option
m = 2.25
Step-by-step explanation:
The slope of the function is equal to its rate of change between two points.
For example, for a couple of points 
The slope is:

In this problem we have the following points
1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)
We calculate the slope between the first two points

We calculate the slope between the points 3 and 4

We calculate the slope between the points 2 and 3

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

Answer:
   61.5°
Step-by-step explanation:
The tangent relation is useful here. The angle is opposite the vertical side and adjacent to the horizontal side of the right triangle.
   Tan = Opposite/Adjacent
   tan(α) = 35/19
   α = arctan(35/19) ≈ 61.5°
The angle made by <em>v</em> and the positive x-axis is 61.5°.
 
        
             
        
        
        
Answer:
there is no slope the answer is undefined
Step-by-step explanation:
the line in this case is a vertical line which would be an undefined line a horizontal line has a slope of zero.
the equation for slope is y^2-y^1/x^2-x^1
 
        
             
        
        
        
The exponent indicates how many times the base is used as a factor.
