I need some assistance with a problem:

Find the slope and the y-intercept of the line y = -x

Thank you!

Re: Slope and y-intercept

Find the slope and the y-intercept
y = -x

y = mx+b
m = -1
b = 0

Where does that leave you?

Hello,

Thanks for your assistance! I have no idea what comes next. I'm totally lost.

I have no idea what comes next. I'm totally lost.

You were taught in class (and in your book, I'm sure) the slope-intercept form, "y = mx + b", where "m" is the slope and "b" is the y-intercept. You've been given (by the tutor) that m = -1 and b = 0.

Where are you still stuck? Please be specific. Thank you.

Eliz.

Ok...the slope-intercept form for the equation of a line is

y = mx + b

In this equation, "m" is the slope, and "b" is the y-intercept.

Your equation is

y = -x

Remember that -x means -1x.

So,
y = -1x

Now, since you don't see any constant added to -1x, one could very safely assume that the contant is 0:

y = -1x + 0

Compare this to slope-intercept form,
y = mx + b

What is the slope? What is the y-intercept?
