Question 1163091
<font face="Times New Roman" size="+2">


Mark the point *[tex \Large (-3,\,4)]


Calculate the coordinates of a second point on the line.  The slope is *[tex \Large -1] which is the same as *[tex \Large \frac{-1}{1}], so the change in the vertical direction is *[tex \Large -1] and the change in the horizontal is *[tex \Large 1].


New *[tex \Large x]-coordinate (horizontal):  *[tex \Large -3\,+\,1\ =\ -2]


New *[tex \Large y]-coordinate (vertical):  *[tex \Large 4\,-\,1\ =\ 3]


So a new point on the line is *[tex \Large (-2,\,3)]


Plot the new point.  Draw a straight line through the two points.


Note: You could also have written the slope as *[tex \Large \frac{1}{-1}] and then added a negative 1 to the *[tex \Large x]-coordinate and added 1 to the *[tex \Large y]-coordinate.  In fact, you could have chosen any number you like, say *[tex \Large a] and added its negative to the *[tex \Large x]-coordinate and its positive to the *[tex \Large y]-coordinate (or vice versa), and achieved the same results.

My calculator said it, I believe it, that settles it
