Answer 2

replace that blank with a variable, say b

so we have `y = x+b`. The goal is to find what number replaces `b`

Answer 3

which point do you see on the diagonal line?

Answer 4

b is 3?

Answer 5

how did you find out that b = 3 ?

Answer 6

With y mx+b

Answer 7

`y = mx+b` you mean?

Answer 8

Yea sorry

Answer 9

and what does b represent in general?

Answer 10

its repersent X? im kinda confuesd

Answer 11

how did you find out that b = 3 ? where did you look on the graph to find that?

Answer 12

I found it using rise over run

Answer 13

but the rise over run is the slope, which is -1/1 = -1 in this case

Answer 14

maybe you're thinking of the y intercept but mixing it up with the slope?

the y intercept is the point where the graph crosses the y axis (the vertical axis), which in this case is 3. So that's why b = 3

Answer 15

and earlier above, the slope is m = -1 because you go down 1, and then over to the right 1

so overall, the final equation is `y = -1x+3` which is the same as `y = -x+3`

Answer 16

Oh Okay thanks Jim!

Answer 17

no problem
