Answer:
D
Step-by-step explanation:
Note: Let us consider, we need to find the gradient of line L.
Given:
The given equation of a line is:

The line L passes through the points with coordinates (- 3, 1) and (2, - 2).
To find:
The gradient of the given line and the gradient of line L.
Solution:
Slope intercept form of a line is:
...(i)
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the gradient of the given line is -4.
The line L passes through the points with coordinates (- 3, 1) and (2, - 2). So, the gradient of line L is:




Therefore, the gradient of the line L is
.

Answer: D. (5,15)</h3>
===========================================================
Explanation:
As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.
The point not fitting this pattern is the point (5,15), so that is the final answer.
For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.
--------------
Alternatively, you can divide each y coordinate by its corresponding x coordinate.
- For choice A, we have y/x = 10/2 = 5
- Choice B has y/x = 15/3 = 5
- Choice C has y/x = 20/4 = 5
All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.
