2. y=2x+3 

When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula.  Then we look at what is changed in the x and y value to determine the m part.  the x increase by 1 and y increase by 2 so the m part is 2. 

3. y=-7x 
Same as the last one, there is no y-inter this time because the y=0 when x=0/  So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.
