Question

The equation of the line of best fit of a scatter plot is y = –8x + 3. What is the the y-intercept?
–8
–3
3
8

Answer 1

So the basic structure of a function is \[y=mx + b\]
m is the slop
x is just x
and b is the y intercept

so you tell me, whats the y intercept

Answer 2

umm i don't know how to find it could you give me a practice problem and show me how.

Answer 3

@Mes_305 : here's a little hint;) There's a saying:
Y=mx+b.
B is where you want to BE on the y axis. Does that help?

Answer 4

umm so is the answer 3

Answer 5

yupp
