Question

Which of the following graph represents the function y = 250x + 2000? Also plot the graph for x = 5, 10 and 15.

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is A

the given function, is y = 250x + 2000

On substituting x = 0 in the equation, we get:

$\text{y = 250(0) + 2000 = 0 + 2000 = 2000}$

So, (0,2000) is a point.

On substituting x = 5 in the equation, we get:

$\text{y = 250(5) + 2000 = 1250 + 2000 = 3250}$

So, (5,3250) is a point.

On substituting x = 10 in the equation, we get:

$\text{y = 250(10) + 2000 = 2500 + 2000 = 4500}$

So, (10,4500) is a point.

On substituting x = 15 in the equation, we get:

$\text{y = 250(15) + 2000 = 3750 + 2000 = 5750}$

So, (15,5750) is a point.

Plotting the points (0, 2000), (5,3250), (10,4500) and (15,5750) on the graph, we get:


So, Option (A) is correct.
