Question

Rowan has $50 in a savings jar and is putting in $5 every week. Jonah has $10 in his own jar and is putting in $15 every week. Each of them plots his progress on a graph with time on the horizontal axis and amount in the jar on the vertical axis. Which statement about their graphs is true?(1) Rowan's graph has a steeper slope than Jonah's.(2) Rowan's graph always lies above Jonah's.(3) Jonah's graph has a steeper slope than Rowan's.(4) Jonah's graph always lies above Rowan's.​

Answer 1

Answer:

Rowan's graph is above Jonah's.

Step-by-step explanation:

let x axis be time

let y axis be money

let t = 0 when Rowan has $50 and Jonah has $ 10.

And at t = 1 week, Rowan has $55 and JonH has $15.

slope of both is 5. Hence lines are parallel. Rowan's graph is above Jonah's graph because Rowan has greater y-intercept i.e, y = $50.
