The formula of a slope:
We have the points (-6, -1) and (-6, 4).
Substitute:
Dividing by 0 is not possible, therefore the slope is undefined.
<em>It's a vertical line x = -6</em>.
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:
Where 
is the slope and 
is the y-intercept.
3. Then, you have that the slope of the function 
is:
Therefore, the answer is: 
You must first link your problems along with the question.
Answer:6
Step-by-step explanation:
You do 6/2 first which is 3 then you subtract 3 from 4 which is 1. Then you multiply 1 by 2 which is 2 and the last step would be multiplying 2 by 3 which is 6
The way I would approach such a question is to put it into equations.
My first equation would be 16x+19y=478 which represents $16 on ski's per person and $19 on snowboards must add up to $478
My second would be x+y=28 because the number of skis and snowboards rented must add up to 28 so each person has one item.
Next you solve them simultaniously. Gonna use elimination
16x+19y=478 (1)
<span>x+y=28 (2) </span>
16x+16y=448 (3 = equation 2 * 16)
(1)-(3) => 3y=30 y = 10.
So now we know that 10 people rented snow boards. Just sub that into eq (2) and get x = 18. So 10 people got snow boards and 18 ski's.
To check, 10x19 = 190
16x18= 228
190+228=478 which works out perfectly!
