Unit 8 - Lesson 4

Today's lesson covered how to write an equation for a line using the slope-intercept form for an equation:

y=mx+b where

m=(y2-y1)/(x2-x1) and

b= y-intercept ( or where the line crosses the y axis).

For your blog, tell me something that you have done in a math class on graphing lines that was more challenging than this or tell me why you think this is so easy.
