finding x intercepts

A

Aaron

I have a formula and have created a list of coordinates and have graphed them
with a line chart and now i need to find the x intercepts of the line.
Thankyou

If you already have the equation, you don't need the points. Just solve the
linear equation. You need algebra, not Excel.

But maybe teacher wants to show that the 'zero of a function' is the same as
its solution.
The OP did not tell us anything about the equation so we cannot offer much
advice.
best wishes

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).
