Answer:

The slope is 3/2.

Step-by-step explanation:

The slope of a line is the relationship between the change of the y-variable and the change of the x-variable. It can be denoted as m = (y2-y1)/(x2-x1), and in layman's terms, it is known as rise over run.

You always can obtain the slope of a line with two points. From this line, for example, I can tell that points (0, 20) and (20, 50) are on the line.

To find the slope of the line, we must first find out what x1, x2, y1, and y2 are. x1 and y1 are the x- and y- coordinates of the first point, and x2 and y2 are the x- and y-coordinates of the second point. With this, we now know that x1 = 0, y1 = 20, x2 = 20, and y2 = 50. We now subsitute this into the formula.

m = (y2-y1)/(x2-x1)

m = (50 - 20)/(20 - 0)

m = (30)/(20)

m = 3/2

Now we know that the slope of the line is 3/2.

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
 SEE ATTACHED IMAGE. 
 
 For this case, what we are going to do is study each part separately. 
 
 Left diagram:
 In this diagram you show three quarters of the hours.
 We have then:
 (3/4) * (12) = 9
 Answer:
 You teach 9 hours.

 Right diagram:
 In this diagram you teach half of the hours.
 We have then:
 (2/4) * (12) = 6
 Answer:
 You teach 6 hours
