Question

Write the equation of the line that passes through (2, 4) and has a slope of –1 in point-slope form.

Answer 1

The other person is correct i just did the test

Answer 2

Point slope form is just a point and the slope written in the form y-y1 =m (x-x1).
Where x1 and y1 (should be subscripts) are (x1,y1) the point you are given.
So in this case all you must do is plug in the given values:

( y-y1 ) = m ( x-x1 )
( y-4. ) = -1 ( x-2 )
This being your answer

I hope this helps!!
