HI friends I will explain lecture 2 from line equation. we will learn deal with interception line . a point intercept the line and find it equation in easily way. many kinds of these problems we solve , you have to focus . share the video to support the free lessons.
so we have this example here
ex) Find the slope of intersection with
the y-axis of a straight given equation:
7x+4y=8
4y=-7x+8
y=(-7)/4 x+2 
We solved the equation for y
We solved the equation for y
This equation in terms of the
intersection with the y-axis and benefit us finding m and b
in this video you will solve more problems
