Question

Use the equation tool to complete the table y=120+18(x)

Answer 1

No need for tool

With Two points is enough to describe this graph

`\left[\begin{array}{cc}(-20)/(3) &0\\0&120\end{array}\right]`

Explanation:

Interception with Y axis (y=0), thus we have the following equation:

`0=120+18*x`

`x=-120/18`

`x=-20/3` since we can not simplify much more

The point for this is (-20/3 , 0)

Interception with x axis (x=0), thus we have the following equation:

`Y=120+18*0`

`y=120`

The point for this is (0, 120)
