Question

How do you graph `y=2x+1` using a table?

Answer 1

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.

graph{y=2x+1 [-16.02, 16.01, -8.01, 8.01]}
