Question

Does (–12, 99) make the equation y = –9x − 9 true?

Answer 1

The equation is given

`y=-9x-9`

The coordinate is given (–12, 99) , substitute in the equation to check it is satisfy or not.

`y=-9(-12)-9`
`y=108-9=99`

which is equal to y values 99.

Hence the point given is satisfy the given equation.
