Chapter 9.2, Problem 7GP

To determine

To find : the two solution of the function

Answer to Problem 7GP

The solution of the function are $\left(0,0\right)$ and $\left(1,10\right)$ .

Explanation of Solution

Given information :

The amount of money Toshiko earn $y$ for working $x$ hours at the library and the linear function is $y=10x$

Calculation :

Step 1 Choose two value for $x$ and substitute each value into the equation. Choose the value0and 1.

Step 2 Evaluate the expression to find the value of $y$ .

$x$	$y=10x$	$y$	$\left(x,y\right)$
0	$y=10\left(0\right)$	0	$\left(0,0\right)$
1	$y=10\left(1\right)$	10	$\left(1,10\right)$

Step 3 explain each solution.

  $\left(0,0\right)$ Toshiko earn 0 for 0 hours

  $\left(1,10\right)$ Toshiko earn 10 for 1 hours

Hence, the solution of the function are $\left(0,0\right)$ and $\left(1,10\right)$ .
