Today in math class we reviewd point slope and slope intercept and learned about standard slope. We learned how to change standard slope to slope intercept and vise versa. Here's an example: x + 4y = 16. To change it to slope intercept, you first need to isolate the "y" variable. So in order to do that, you divide by 4 for 4y and 16. That will then give you x + y = 4. But it is understood that "x" is 1 and so the slope intercept is:
y = -1/4x - 4 and there you have it! So to change -3/5; (-2,-4) to standard form. First you need to put it in point slope to find the y-intercept.
Example:
1. y + 4 = -3/5 (x - -2)
2. y = -3/5x +2 -4
3. y = -3/5x - 5 1/5
So my standard form is 3x - 5y = 26.
