Week 13 – Math 10

This week in math 10 we learned how to write and equation of a line in general form form. Bellow are some examples and descriptions of how to do general form.

  1. y = -2x + 9

So you have this equation and basically all you need to do is get a zero on one side of the equation by itself.

So subtract the y and you get           0 = 2x – y + 9

2.   y – 4 = 7(x – 1)

y – 4 = 7x – 7                     so you have to distribute first, now get zero on opposite of the equation

y = 7x + 4 – 7

0 = 7x -y – 3
