Graph the function y=x-5. What is the zero of this function?*
ioda

Answer:

(5,0)

Step-by-step explanation:

"The zero" means the 'x-intercept' of the graphed equation.

That gives you the value of x (first number in the pair) that you substitute in the equation to make it true to get  the value of y  being 0, (the second number in the pair.

y = x - 5 substitute 0 for y and 5 for x and check

0 = 5 - 5   True.

Or to solve if no choices are there to select

0 = x-5      add 5 to both sides of the equation

0 + 5 = x -5 + 5   -5 +5 = 0

5 = x

Ot graph the equation
