Question

choose the equation of the line with slope

Answer 1

y = mx + b

m = -6/5
x = 0
y = 9

Plug these values in and solve for b.

9 = (-6/5)*0 + b
b = 9

So: y = -6x/5 + 9

Answer 2

Btw, if you're just posting questions without having read the book it's really not a good idea. Try to read your book or Paul's notes if your book isn't so great.

Answer 3

b/c believe it or not, you really need to know this stuff in the higher level maths.

Answer 4

I agree.

y = mx +b is the place to begin.
