Question

Determine the equation of the line give the point (25, 75) and the slope m= -9.

Answer 1

`y-75=-9(x-25)`

Explanation:

There is enough information given to write the equation in point slope form.

The point slope equation is:
`y-y_(1) =m (x-x_(1))`

Where m is the slope and (25, 75) would be x1 and y1.

Plug the numbers into the formula:

`(x_(1), y_1) = (25, 75)\\m= -9`

---------------------

`y-75=-9(x-25)`
