Erin set up a lemonade stand to earn money. When she started her lemonade stand, she had $5. She sells each glass of lemonade for $2.

This scenario is modeled by the function equation f(x) = 2x + 5.

Which graph represents the equation?

Answer 1

Answer: The first graph (the steeper one)

Explanation:

The vertical axis intercept is 5 and the slope is 2/1 or 2.

Answer 2

The first graph.

Explanation:

Erin started with $5, so the graph would start at 5, because that's her starting number. She earns $2 for every 1 glass of lemonade she sells, so the graph would have to go up 2 numbers every time it goes 1 number to the right. If you know slope, the slope would need to be 2/1.
