How to solve this graphing problem?

Question

Graph a line through (-2, 2) that is parallel to a line whose slope is -1?

I know how to graph, but I'm not sure on how to do the math.

Answer 1

there really is no math in it... all you do is make a point on the graph at (-2,2) and (-1,1), and then draw the line. if you need the equation, plug in the point to the equation y=mx+b.

2=(-1)(-2)+b
b=0
y=-1x
thats about it
