how to find slope and y-intercept

Submitted by loganharris3217 on 20. April 2007 - 0:42

i need help in find slope and y-intercept

there are equations like this:

y+3=-1/3x

y-2x=-3

y-6=-2x

what are the stpes to solve them?

and how to solve them?

To find slope and intercepts

Submitted by Tutor on 20. April 2007 - 2:54.

To find slope and intercepts of line just write them in general form of equation of line

y=mx+c , in this m is slope and c is the intercept

Lets see one example

y-6=-2x

Rewrite it in the form y=mx+c

y= -2x+6

Comparing we have

m=-2 and c= 6

So slope of line is -2 and intercept is 6

To see why it has intercept of 6 , just see the point at which it cuts the y axis in graph above

now try to do other parts and let me know
