Set the equation in standard line format (slope, intercept format):
Y = mX + b
m is slope
b is y-intercept
Since there is no constant shown, the constant is zero --> Y-intercept is zero
Then use the slope to plot another point (slope = rise/run =  change in Y divided by change in X)
Connect the dots and extend the line
first divide everything by 5
y= -2x
now to graph, start at zero then go down two over 1... then repeat ;)
