@iGreen

Answer 3

First, tell me what the y-intercept is.

Answer 4

The y-intercept is the point where the line crosses the y-axis, and where is that?

Answer 5

4?

Answer 6

No, check again

Answer 7

is it negative?

Answer 8

Yep, -4.

Answer 9

Now we have the y-intercept.

y = mx + b where 'm' is the slope and 'b' is the y-intercept.

So far we have:

y = mx - 4

Now we find the slope.

Take any two points, let's take (0, -4) and (1, 0) and plug them into the slope formula.

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

\(m = \dfrac{0+4}{1-0}\)

Simplify that

Answer 10

4/0?

Answer 11

idk?

Answer 12

4 is correct, but 1 - 0 isn't 0. Check again

Answer 13

Can you subtract 1 - 0? @becker2000

Answer 14

i mean 1

Answer 15

@iGreen, Sorry Please come back

Answer 16

Yep, now divide 4 / 1

Answer 17

4

Answer 18

So is it B?

Answer 19

Yup, you got it.

y = 4x - 4
