Answer:
196
Step-by-step explanation:
find the slope with y2-y1 / x2-x1
points (7, 1372) and (12, 2352)
(2352- 1372) / 12-7
= 196

1. 0.91<0.93; 0.91 is farther away from the whole number 1 so it is less than 0.93.
2. 0.5=0.50; 0.5 and 0.50 are the same, since the decimal can be written with or without the zero.
3. 1.08<1.6; 1.08 is farther away from the whole number 2, so it is less than 1.6.
In a simple Cartesian plane, there are two axes, y-axis that is drawn vertically and the x-axis that is drawn horizontally. this problem asks for the an example of horizontal stretch. Thus, the example of horizontal stretch is the stretching of the graph away from the x-axis. Thus, the answer is letter C.
