Question 431951: I would like to know did I do this correctly. email address is sowellsamantha@yahoo.com
Ax + BY = C
3y = -9X -12
-3 -3
-3y = -9x -12
-3 -3 -3
In slope intercept form y = 3x + 4
Slope is (m) which equalizes m = 3
My next question is
Assign coordinates for any two points: A( ..., ...) B( ..., ...).
Calculate slope of line passing through these points.
Find equation of this line in a form: y = mx + b

-3 -3
-3y = -9x -12
-3 -3 -3
In slope intercept form y = 3x + 4 **** It's y = -3x - 4, just divide by 3

m = -3

Hi

3y = -9x-12 OR y = -3x-4   |m = -3



|Using the point-slope formula, 

(5,6)

(2,3)  m = 3/3 = 1    

 y = mx + b

 y = x+ b

 6=  5 + b   |using Pt(5,6) to find b

 1 = b

 y = x+1
