**Answer:**

A

**Step-by-step explanation:**

Try plotting some sample values, you will notice it goes toward the x axis, but will never intercept it

First of all, we have to draw the line. Sample any two points from the line, for example choosing x=0 and x=2: if x=0, the equation becomes y=2, and thus the line passes through (0,2)

If x=2 the equation becomes y=0, and thus the line passes through (2,0).

Draw the line passing through these two points, and you'll have the line of option B.

Since the inequality is of the type , we are interested in all the points **above** the graph, so again, option B is correct.

**Answer:**

**Step-by-step explanation:**

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are** 'x' number of questions** in the exam and **'t' is the total time taken to finish the exam, in minutes**. So the time taken to complete the exam would be

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam
