What are the intercepts of #y=2x-4#?
To find intercepts, you make the other variable zero. For example, to find the x-intercept, y=0.
But with the given equation, it is not necessary to make x=0 to find the y-intercept, since it is already in slope intercept form (y=mx+b)
The b is always the y-intercept. The sign goes with, meaning the negative goes with the four.
If you substitute y as 0, you can see that x is then 2.
Hope this helps B)...
