Question

help with finding the y intercept

Answer 1

Can you post the question?

Answer 2

the y intercept is when x =0

in this case it is the value in his account at the beginning of the question.

you are told this value in the question

Answer 3

Well how much did he have saved at 0 days?

Answer 4

234$

Answer 5

Then that is your y-intercept. When the x value is at 0, the y value will be your y-intercept. Also, the dollar sign is before the number fyi

Answer 6

lol i realized that after i posted it
thx

Answer 7

ye no problem (:

Answer 8

Answer 12

No no no. I thought we already established what the y-intercept is. What is his starting value?

Answer 13

$234

Answer 14

Well the starting value is the y-intercept. The starting value is the value when the days = 0, so that is what makes it the y-intercept.

Answer 15

y=mx+b
y=0x+234
????????????

Answer 16

\[\large \sf y=mx+b\]\[\large \sf y=2.1x+234\]\[\large \sf y=2.1(0)+234\]\[\large \sf y=0+234\]\[\large \sf y=234\]

Answer 17

ohhhh
