Question

If (x, 1/100) lies on the graph of y = 10x, then x =

Answer 1

1

--------- = x

1000

Explanation:

Copy down y = 10x.

Then substitute 1/100 for y:

1

-------- = 10x

100

Divide both sides by 10 to isolate (solve for) x:

1

--------- = x

1000

Answer 2

The value of x in the coordinate is 1/1000

Using the coordinates of the point given:

• (x , 1/100)

Equation of the graph:

• y = 10x

To find the value of x for the coordinate given; substitute into the equation:

1/100 = 10x

1/100 × 100 = 100 * 10x

1 = 1000x

x = 1/1000

Hence, x = 1/1000
