Answer 1

what do you say?

Answer 2

False?

Answer 3

why?

Answer 4

Because the graph is going downward. Right?

Answer 5

\[\Large y=mx+b\]
m is the slope

b is the y-intercept

Answer 6

m is negative ... then the graph MUST go downward

Answer 7

Wait.. so it's true?

Answer 8

No no, false?

Answer 9

y goes down by 4, as x goes up by 1

so, m=-4

Answer 10

Alright, so that means false because m isn't -4 on the graph.

Answer 11

the graph meet y-axis at y=+4

so, b=+4

s, y=-4x+4 true

Answer 12

Ohh! Wow, I'm so slow. Well, thanks. :)
