The y intercept is the point at which the line crosses the y-axis and the x-intercept is the point at which the line crosses the x-axis. Crossing the y-axis means x=0 and crossing the x-axis means y = 0.

\n" ); document.write( "What this means in this case is, set x = 0 to get y = 2*0 + 1 = 1. In other words, when x = 0, y = 1, so the y-intercept is (0,1). Next, set y = 0, so 0 = 2x + 1. To solve for x in this case, subtract one form both sides to get -1 = 2x, then divide both sides by 2 to get $\"x+=+-%281%2F2%29\"$ . The x-intercept is ( $\"-%281%2F2%29\"$ , 0). \n" ); document.write( "
