Question

6. The costs for going to a dog beach are

$7 for 1 dog, and $2 for each additional
dog. Which equation shows this situation,
where x > 1?
A y = 2x + 5
Cy= 5x + 2
B y = 3x + 11 D y = 7x + 11

Answer 1

9514 1404 393

Answer:

A y = 2x + 5

Explanation:

The cost per dog is the slope of the cost equation, 2. The equation can be written in point-slope form as ...

y -7 = 2(x -1) . . . . using the point (1, 7)

Simplified, this is ...

y = 2x -2 +7

y = 2x +5 . . . . matches choice A
