Start by drawing an x-axis (horizontal line) and y-axis (vertical line) on a piece of graph paper. Label where the 2 lines intersect as (0,0). This is the point where x=0 and y=0.

Next, start plugging in values for x into the equation to find the corresponding y value, and plot the points on the graph.

x=0, y=-2(0)+1=1

x=1, y=-2(1)+1=-1

x=-1, y=-2(-1)+1=3

When enough points are plotted, connect the dots with a ruler - the answer should be a straight line.
