Answer 3

The first function is in the form of:

y = mx + b

Where 'm' is the slope and 'b' is the y-intercept.

So what's the y-intercept of y = 0.3x + 3.4?

Answer 4

How do i find that out?

Answer 5

Compare

Answer 6

y = 0.3x + 3.4
y = mx + b

'm' is slope 'b' is y-intercept

Therefore 3.4 is the y-intercept, understand?

Answer 7

Not really

Answer 8

Which of the following relations is not a function?

(-4, 4), (0, 2), (9, 1), (-6, 5)

(-6, 4), (0, 3), (-4, 1), (9, 2)

(9, 4), (-4, 2), (0, 1), (-6, 2)

(0, 4), (-4, 2), (0, 1), (-6, 2)

Answer 9

Which one?A,B,C,or D

Answer 10

Functions can only have 1 x-value.

Answer 11

The x-values in option A are:

-4, 0, 9, and -6

Are any of those the same?

Answer 12

No!

Answer 13

Which of the following relations is not a function?

(-4, 4), (0, 2), (9, 1), (-6, 5)

(-6, 4), (0, 3), (-4, 1), (9, 2)

(9, 4), (-4, 2), (0, 1), (-6, 2)

(0, 4), (-4, 2), (0, 1), (-6, 2)

Answer 14

Which one ABC or D

Answer 15

Yes, so A is incorrect, because it is a function.

Answer 16

Look at option D, it has x-values of 0, -4, 0, and -6.

Answer 17

Are any of those the same?

Answer 18

yeah 0

Answer 19

Yes, so that's your answer

Answer 20

Because it has 2 x-values, it is not a function.
