the answer depends on the equation. To find x-intercepts you need to set Y =
0 and solve for X. This may be simple or complex. Post the equation if you
have problems. There are ways to estimate the X intercepts for complex
equations. You can always write a program. also post how accruate you need
your answer (number of decimal places).

with a line chart and now i need to find the x intercepts of the line.
Thankyou
