g(x)= -2x

g(x) is just a complicated way of saying y

y = -2x

To graph a point put in a value for x

-1, 0, and 1 are usually easy values to put in

if x=0 y=0 so (0,0) is a point on the graph

if x=1 y= -2 so (1, -2) is another point on the graph

Now that you have two points draw a straight line through the two points. there's your graph.
