sketch the graph of the given linear function.
y=5

Homework Equations

The Attempt at a Solution

im unsure of how to do this one without having an x, would x just be undefined and y would be equal to 5.

Make a table of values. For x = 0 y = ? x = 1, y = ? etc. then plot it.

ya but for this one wouldn't x just be undefined since its not given and then it would just be a horizontal line through y=5.

Yes it is a horizontal line through (0,5). It also passes through (1,5), (2,5), (3,5) etc. Just because x is missing in the equation doesn't mean x is "undefined". It is sort of trivial to list a table of values, but it would include the three points above plus as many others as you want. You could think of it as y = 5 + 0*x, a line with slope 0 and y intercept 5.
