Assumption: You mean the question as written.

Given: $y=-1/2+3$

$=>y=2 1/2 = 2.5$

What we have is $y="some constant value"$

This situation results in a straight line that is parallel to the x-axis and passes through the point $(x,y) =(x,2 1/2)$

In other words: you can use any value you wish for $x$ but $y$ is always $2 1/2$

Assumption: You mean the question to be $y=-1/2+3x$

One of the standardised forms is $y=mx+c$

Where $m$ is the gradient (slope) and $c$ is the y-intercept.

Thus we have:

$y=mx+c color(white)("d") -> color(white)("d") y=3x-1/2$
