Answer:
The equation of the line in point-slope form is 
.
Step-by-step explanation:
According to the statement, let 
and 
. The equation of the line in point-slope form is defined by the following formula:
(1)
Where:
, 
- Coordinates of the point A, dimensionless.
- Slope, dimensionless.
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
In addition, the slope of the line is defined by:
(2)
If we know that 
and 
, then the equation of the line in point-slope form is:
From (2):
By (1):
The equation of the line in point-slope form is .
Answer:
1. 7.66 x 10^4
2. 2.415×10²
Step-by-step explanation:
2. 8×105-5.7×105=241.5
It opens upward and the vertex is (2,-6) here are some plotted points: (0,6),(1,-3),(2,-6),(3,-3),(4,6). Hope that helps. I hate graphing but if you do it enough times you'll get the hang of it!
Algebra is Faster And Better Than “Basic” Math
Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
