# MPM2D Lines in y=mx+b form 2016-09-12

Today we reviewed finding equations for lines in three different scenarios:

• you have a graph
• you have a point and the slope
• you have two points

I handed out this page, and assigned the following questions for homework:

Find an equation in $y=mx+b$ form for each line below:

1. Point $(2,2)$ and slope $m=-5$
2. Point $(\frac{1}{2},-\frac{1}{4})$ and slope $m=-\frac{1}{4}$
3. Point $(7,-3)$ and slope $m=2$
4. Points $(2,3)$ and $(-3,5)$
5. Points $(7,0)$ and $(0,7)$
6. Points $(5,1)$ and $(5,-4)$
