Question 810232: i need some help with y and x intercepts

You can put this solution on YOUR website!
I'll pick an equation to demonstrate
+y+=+-2x+%2B+6+
Here's the plot:
+graph%28+400%2C+400%2C+-2%2C+10%2C+-2%2C+10%2C+-2x+%2B+6+%29+
You can see the intercepts
(1) x-intercept is at ( 3,0 )
(2) y-intercept is at ( 0,6 )
-----------------------
This is normally shortened a little by just saying:
(1) x-intercept is at 3
(2) y-intercept is at 6
-------------------
Where the line intercepts the x-axis, +y+=+0+
Where the line intercepts the y-axis, +x+=+0+
This is the key to finding the intercepts
--------------------
x-intercept:
+y+=+-2x+%2B+6+
+0+=+-2x+%2B+6+
+2x+=+6+
+x+=+3+
so, the x-intercept is 3
--------------------
y-intercept:
+y+=+-2x+%2B+6+
+y+=+-2%2A0+%2B+6+
+y+=+6+
so, the y-intercept is 6
Hope this helps
