Question

Use the graph to write a linear function that relates y to X.

Answer 1

Linear function that relates y to x.

y = x

coordinates of y = x

$| \ \ x \ | -2 \ | \ -1 | \ \ 0 \ | \ \ 1 \ | \ \ 2 \ | \ \ 3 \ \ \ | \\ --------------\\ | \ \ y \ \ | -2 \ | \ -1 | \ \ 0 \ | \ \ 1 \ | \ \ 2 \ | \ \ 3 \ \ |$

---------------------------------------------------------------------------------------------------------

A linear function is a straight line following equation: y = mx + b

                                                              where m is slope, b is y-intercept

Answer 2

⚘ Refer to the attachment for graph and below for some details!~

Details ⤵️

• x-intercept = 0
• y-intercept = 0
• slope = 1
• Domain = x∈R

It is a linear function. Since, the line is straight when it's plotted and the linear function is (y=x)

Some X and Y coordinates are:

$\begin{gathered}\boxed{\begin{array}{c|c}\boxed{\sf x} &\boxed{\sf y} \\ \sf -2 &\sf -2 \\ \sf -1 &\sf -1\\ \sf 0 &\sf 0 \\ \sf 1 &\sf 1\\ \sf 2 &\sf 2 \end{array}}\end{gathered}$
