Question

Alex had $234 in his bank account. For an entire month, Alex adds $2.10/day to the account. He graphs the money he saves versus time. He plots money saved along the vertical axis, and he plots time in days along the horizontal axis.

What is the y-intercept of the line?

Answer 1

@Miracrown

Answer 2

He starts with $234 and each day he adds $2.10. So on day 0, he has $234.

day 1: $234 + 2.10
day 2: $234 + 2 * 2.10
day 3: $ 234 + 3 * 2.10
day 4 : $234 + 4 * 2.10

Do you see the pattern?

Answer 3

What equation can we write (in terms of days)?
