12.4 Linear function f(x,y) = zo+m(x-xo)+n(y-yo) Or f(x,y) = c+mx+ny For fixed y, m = dz/dx ……….for fixed x, m = dz/dy Linear fit dx is rows and dz is colums with (y fixed) And dy is columns, while dz is rows with (x-fixed) Must have pattern to be linear in graph form Using linear formula: Find eq of linear function who contain (0,0,0) (0,2-1) and (-3,0,-4) Plug in all through pt values separately

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
