Is every linear equation a linear function? yes or no? explain

While all linear equations produce straight lines when graphed, not all linear equations produce linear functions.

explanation

In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

not all lines are linear i really don't remember how to find if it is linear but i know that not all of them are

add 5 subtract 1

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
