OBJECTIVE: SWBAT USE WHITE BOARDS TO GROUP LINES USING POINT SLOPE FORM

Today in class, we went over standard form again and learned how to actually do it this time. Another name for standard form is STD, not the disease though. The formula for standard form is Ax+By=C. Learning this was very confusing. It still is but, I can understand it better than before. An example is shown below about how to do this.

EXAMPLE:

Ax+By=C

***m= -Ax/B; b= C/B***

3x+2y=10

2y=-3x+10

    -Subtract 3x from both side

y=-3x/2+ 10/2

    -Divide everything by two

y=-3x/2+5

    -Reduce and you are done!

    -You know you are done if the answer looks like y=mx+b
