Request Description

The similarities and differences between functions and linear equations is the fact they are set up the same. Example: 4q-3p=22. Also, in a linear equation you have “x” and “y” which forms an ordered pair and in a function you have your one set to another or your domain and your range which determines your function. Differences could include when solving a linear function you solve for x and y and when solving a function you solve for x and f(x). Also in a function only one domain can equal to one range. Most linear equations are functions (that is, for every value of *x*, there is only one corresponding value of *y*). When you take x and plug it into y = mx + b, you get one and one only possible value back for y. Granted you can draw a LINE that's not a function, like the line "x = 6"; however this is not a linear equation since there is no way to put it in the form of y = mx + b.

Example:

x^2+y^2=4

X=y^2
