Algebra SUCKS! Can I have someone's help?

Question

f(x)=-7x-9 is the equation. The question asks me the slope.

I say -7 is the slope.

It also asks me what the y-intercept is.

I say that is -9.

Am I correct???

Answer 1

Yep. Exactly... because the formula is y=mx+b

m=slope

b=y-intercept

Answer 2

Yes, you are. And algebra is effing easy, calculus however sucks big time!

Answer 3

f (x) = - 7x - 9

slope , m = - 7---------You are correct !

y intercept is y = - 9-----You are correct !

x = - 4 is a vertical line that passes thro (- 4 , 0)

The slope of this line is not defined.

Answer 4

yes you are

Answer 5

Algebra doesn't suck.  Some people just suck at doing it.

Anyway, you are correct.  When you have an equation in the form of y = mx+b (or for that matter, f(x) = mx + b), then "m" is the slope and "b" is the y-intercept.

Answer 6

            correct

Answer 7

This is a form of y=mx+b, but with y replaced by f(x). (m) is the slope & b is the y-intercept. You are correct.

Answer 8

Yes you are correct! BTW algebra does NOT suck!)

Answer 9

That function is in slope-intercept form.

f (x) = mx + b, where m is the slope and b is the y-intercept.

The slope is -7, and the y intercept is -9.

You are correct!

Answer 10

Yes.  Algebra doesn't suck as much as you thought.
