Answer:
The gradient of the straight line that passes through (2, 6) and (6, 12) is
.
Step-by-step explanation:
Mathematically speaking, lines are represented by following first-order polynomials of the form:
(1)
Where:
- Independent variable.
- Dependent variable.
- Slope.
- Intercept.
The gradient of the function is represented by the first derivative of the function:

Then, we conclude that the gradient of the staight line is the slope. According to Euclidean Geometry, a line can be form after knowing the locations of two distinct points on plane. By definition of secant line, we calculate the slope:
(2)
Where:
,
- Coordinates of point A.
,
- Coordinates of point B.
If we know that
and
, then the gradient of the straight line is:



The gradient of the straight line that passes through (2, 6) and (6, 12) is
.
Answer:
-25,-6
Step-by-step explanation:
5 to - 10 is a 15 unit negative transition on the x axis
2 to -2 is a 4 unit negative transition on the y axis
45000 is the answer because 1800 x 25 = 45000
