Question

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

O (5,0)
O (0,5)
O (-5,0)
O (0,-5)

Answer 1

(5,0)

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
