Question

Brent has a model car collection. He was given 3 cars as a gift, and he adds 4 cars per year. Which of the graphs below represents Brent's model car collection?

Answer 1

Well there isn't any graphs shown here but it would be the one that on the y-axis, would start on the 3 and go up 4 and over 1 per year.

Answer 2

Answer: The below graph represents Brent's model car collection.

Explanation:

Let x represents the number of years and y represents total car Brent has.

Here, Brent has a model car collection. He was given 3 cars as a gift, and he adds 4 cars per year.

Thus, the total cars Brent has,

y = 4 x + 3

Which is the equation of line that shows the given situation.

The line has x-intercept = ( -3/4, 0)

And, y-intercept = (0,3)

If x= 1 y = 7

If x=2, y=11

If x=3, y=15

If x=4, y= 19

Thus, the line has the following points,

(1,7), (2,11), (3,15) and (4,19)

Hence, with the help of the above information we can draw the graph of the given situation.
