Trying to figure out my sons math. been way to long!!!!

The question is find the slope for
y = 3

There is no slope. There is no X in that equation. On a graph it would be plotted as (0,3)

look at y = 3 as

y = 0x + 3

so the slope of the line is 0
You are looking at a horizontal line

To find the slope of the equation y = 3, we first need to identify the format of the equation.

In this case, the equation y = 3 is in the form of a horizontal line with a y-coordinate of 3.

A horizontal line has a slope of 0 because the y-coordinate does not change. In other words, the line is parallel to the x-axis and does not have any vertical movement.

So, the slope of the line y = 3 is 0.
