Question

I am not sure what the answer is but I wanna make sure that my answer is correct.

The description below represents Function A and the table represents Function B:

Function A

The function is 5 more than 3 times x.

Function B

x y
-1 2
0 5
1 8

Answer 1

Which statement is correct about the slope and y-intercept of the two functions?
Their slopes are equal, but y-intercepts are not equal.

Their slopes are not equal, but y-intercepts are equal.

Both slopes and y intercepts are equal. I think it's this one

Neither slopes nor y intercepts are equal.

Answer 2

why?

Answer 3

I understand that the equation for function A is written like this

y = 5 + 3x

Answer 4

btw, i'm not saying you're right or wrong... just want to know your thinking

Answer 5

very good

Answer 6

and for B?

Answer 7

Well, heres what I did

-1 * 3 = -3
-3 + 5 = 2

Answer 8

then 0 * 3 = 0
0 + 5 = 5

Answer 9

1 * 3 = 3
3 + 5 = 8

Answer 10

very good! you can see from the table data that every time you increase x by 1, y increases by 3. that's the slope. and when x = 0, y = 5, that's the y intercept.


great job and you are correct!

Answer 11

okay thanks! :0

Answer 12

wait sorry that :0 was supposed to be a :) lol

Answer 13

no worries!
