f(x) = 2x
the standard form for a line is y = mx +b where m is the slope and b is the y-intercept
the given equation y = f(x) = 2x, the slope is 2 and the y-intercept is 0
if x is 1 then y = 2 and point to be plotted is (1, 2)
if x is 0 then y = 0 and point to be plotted is (0, 0)
if x is -1 then y = -2 and point to be plotted is (-1, -2)
graph of line is
