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
xcolor(white)(.......)y
0color(white)(.......)1
1color(white)(.......)3
2color(white)(.......)5
3color(white)(.......)7

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