Answer:

See the explanation.

Explanation:

#y=2x+1#

Since this is the slope-intercept equation for a straight line, the table only needs two points. However, I'm going to determine #4# points (ordered pairs). Determine values of #x#, then calculate #y#.

Ordered Pairs
#x##color(white)(.......)y#
#0##color(white)(.......)1#
#1##color(white)(.......)3#
#2##color(white)(.......)5#
#3##color(white)(.......)7#

Plot the points on a graph and draw a straight line through them.
