*group 3, y=mx+b m; in order to find m u have to fin the slope of the…

- - - - Find the slope=m of the equation y = mx + b.
        
        plot the y-intercept. The point will be (0, b).
        
        To graph a line you have to find the y-intercept = b of the equation y = mx + b.
- - - - the points in red are called lattice points, its when the line runs over a corner on a square grid

        now that we know how to calculate a slope, lets see what a slope formula means
        
        to calculate a slope formula it needs 2 points.
        
        for example (4,3) and (3,2) both ranges subtracted from each other and both domains subtracted from eachother.
        
        3-2=1
        4-3=1. the answer would equal 1.
