Answer 2

Which equation best compares the slopes of the two functions?

Slope of Function B = 2 × Slope of Function A.

Slope of Function A = Slope of Function B

Slope of Function A = 2 × Slope of Function B

Slope of Function B = - Slope of Function A

Answer 3

Okay, find the slope of function B first

Answer 4

Slope is rise over run, or y-difference divided by x-difference

Answer 5

Use any two points on the line to find the slope

Answer 6

ok so...

Answer 7

how if there re no points

Answer 8

You create two points on the line

Answer 9

(0,-1) and (1,1) are good points

Answer 10

ok so -1 - 1 = m(0 - 1)

Answer 11

-2 = m(-1)

Answer 12

-2 = -m

Answer 13

And m=?

Answer 14

2?

Answer 15

Yep

Answer 16

Find the slope of function A?

Answer 17

-7?

Answer 18

Why?

Answer 19

no i meant -9

Answer 20

or wait -5

Answer 21

Why and why?

Answer 22

well bec -2 - 9

Answer 23

equals... ohhhh, 7?

Answer 24

Why -2-9?

Answer 25

Remember that in the form y=mx+b, m is the slope and b is the intercept

Answer 26

omg its getting late just cut to the poop

Answer 27

So in f(x)=x-9, the slope is 1

Answer 28

So the answer is A

Answer 29

which one a b c or d

Answer 30

ok thanks
