Question 666612: y=3x+2
y=-4x+2
why does my professor show me so many steps--its confusing
unles im incorrect, i know the y int is 2 and the slope is three-we did this on the board in class as a whole but I want to see it done in a much more simpler fashion:)
Thanks!

Hi,

Using the standard slope-intercept form for an equation of a line y = mx + b

  where m is the slope and b the y-intercept.

Doesn't get simpler than that:

y = 3x+2   Yes.  m = 3 and the y=intercept is 2   Green

y= -4x+2    m = -4  and the y=intercept is 2      Blue
