Let's say that the unknown value here is c. Although we are given two points on the line, it is only necessary to use one as there is only one unknown value, so let's say we choose the point (6, -12) and substitute this into the equation:
-12 = 1(6) - c
-12 - 6 = -c
-18 = -c
c = 18
Thus the equation for the line is y = 1x - 18
Answer:
The linear equation for Shana's elevation is
.
Step-by-step explanation:
According to the statement, we find that Shana is climbing at constant rate in time and height as a function of time can be represented by linear function:
(Eq. 1)
Where:
- Initial height above sea level, measured in feet.
- Elevation above sea level, measured in feet.
- Climbing rate, measured in feet per minute.
- Time, measured in minutes.
If we know that
,
and
. the initial height above sea level is:



The linear equation for Shana's elevation is
.
Since the perimeter of the square is 28ft, the side length of the square is 7ft.
Hence, the area of the square is 49 square feet.
40-15=25 students not on student council
25/40 = .625 decimal
multiply by 100 to get percent
62.5% of students are not on student council
Estimating:
15 rounds to 20 and 40 rounds to 50
40% are in student council and that leaves roughly 60% not in student council.
