Question

For y = 3x + 10, list 4 Solutions to this equation in coordinate pair (x,y) format

Answer 1

`\begin{gathered} (1,13) \\ (2,16) \\ (3,19) \\ (4,22) \end{gathered}`

Explanation:

To list 4 solutions in the function below, we need to use 4 x-values and use y(x) to get the y coordinate.

In this case, let's use x=1, x=2, x=3 and x=4.

For x=1.

`\begin{gathered} y(1)=3(1)+10 \\ y(1)=13 \\ \text{Then, (1,13) is a solution.} \end{gathered}`

For x=2.

`\begin{gathered} y(2)=3(2)+10 \\ y(2)=16 \\ \text{Then, (2,16) is a solution.} \end{gathered}`

For x=3.

`\begin{gathered} y(3)=3(3)+10 \\ y(3)=19 \\ \text{Then, (3,19) is a solution.} \end{gathered}`

Finally, for x=4.

`\begin{gathered} y(4)=3(4)+10 \\ y(4)=22 \\ \text{Then, (4,22) is a solution.} \end{gathered}`
