Question

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

Function A

The function is 8 more than 3 times x.

Function B

x

y
-1

2
0

5
1

8


Which statement is correct about the slope and 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.

Neither slopes nor y intercepts are equal.

Answer 1

Function B

x y
-1 2
0 5
1 8

Answer 6

A : 8 more than 3 times x -----> 3x +8
right ?

Answer 7

Correct

Answer 8

x,y
-1,2
0,5
1,8

Answer 9

like that?

Answer 10

Yes, like that Shamil.

Answer 11

for function B , you have 2 points (infact 3 , use any 2)
and try to find the slope.

Answer 12

Yeah, then compare it with the slope of y = 3x + 8
m = 3/1

Answer 13

m=4?

Answer 14

no, how?

Answer 15

-1,2
0,5
y2-y1 / x2 - x1

5 - 2 / 0 -(-1) = m

Answer 16

Sorry, my bad.

Answer 17

m=3 for function B

Answer 18

OR -3?

Answer 19

yes 3 , and the equation ?

Answer 20

y=mx+b

Answer 21

So the slopes for functions A&B are definitely the same.

Answer 22

So we can eliminate the second and fourth answers

Answer 23

yes.
to get 'b', put x=0 in y=mx+b

Answer 24

and y= 5
since 0,5 lies on the line

Answer 25

y=3*0+b
y=0+b
y=b

Answer 26

so, b=5, right ?

Answer 27

So y-intercepts are NOT equal, choice A is correct?

Answer 28

Yes b=5

Answer 29

yup.

Answer 30

How did you know that (0,5) thing

Answer 31

x y
-1 2
0 5
1 8

3 points are (-1,2) , (0,5) and (1..8)

Answer 32

(1,8)

Answer 33

i can choose any one to find b

Answer 34

Oh ok, thank you!

Answer 35

welcome ^_^

Answer 36

You are correct
