The intercepts of the graph will be (0, ?) and (?,0).

Explanation:

First, let y = 0 and solve for x: #0 = 2x + 1# so #-1 = 2x#
therefore #-1/2=x#. Your x-intercept is (#-1/2,0#).

Find the y-intercept by substituting x = 0: #y = 2*0 + 1#
so y = 1. Your y-intercept will be (0,1).

Plot these points and make your graph: (see below)
