How do you find the x and y intercept of a line?

Question

Man I forgot how to find it .... it's kinda true that you forget a lot of stuff over summer vacation :]

Answer 1

hmmm, i think its the x intercept is where it cuts the line on the x axis (the one goin across)

and the y intercept is where it cuts the line on the y axis (the one goin upwards)

i think...

Answer 2

Pick the intercept that you want to find first.  And for explanation purposes, let's say you want to find the x intercept first.

All you have to do is substitute zero for y into the equation and solve for x.  x will equal some value.  That value will be the x intercept of the line.  

You do the exact same thing to find the y-intercept too, only you substitute zero for x in that case, and solve for y.

Another way to find the intercepts would just be graphing the line and seeing where it crosses the x axis and the y axis.

explains nicely..its a good site for math

the guy above me just told you how to find slope..

Answer 4

y2-y1 divided by x2-x1

rise over run
