Question

Help please and thankyou Graph the function below: y = 3x + 1

Answer 1

By definition, a single line passes through two points, then you can give x two values ​​to obtain two points of the line and thus be able to graph it.

Then, if for example you take x = 2 and x = 3 you have

`\begin{gathered} \text{If x=2} \\ y=3x+1 \\ y=3(2)+1 \\ y=6+1 \\ y=7 \\ \text{ So, if x = 2 you have the point (2,7)} \end{gathered}`
`\begin{gathered} \text{If x=3} \\ y=3x+1 \\ y=3(3)+1 \\ y=9+1 \\ y=10 \\ \text{ So, if x = 3 you have the point (3,10)} \end{gathered}`

Now graphing you have
