How can you find zero of a linear function feom an equation, graph, or table?

If you're given a function, you replace f(x) or y with 0 and solve for x.

For example, y = 5x-10 is solved like so

y = 5x-10

0 = 5x-10

-5x = -10

x = -10/(-5)

x = 2

Showing that x = 2 is the root to y = 5x-10. The term "root" is the same as a solution or a zero of a function.

If you're given a graph, you look to where the graph crosses the x axis to find the roots. These locations are known as the x intercepts. The graph may cross the x axis or it might touch the axis and bounce back.

If you're given a table of values, you look for when y is equal to 0 in the table. Whatever x value(s) pairs with y = 0 is your answer(s). This backs up what was mentioned at the top of this solution.
