Algebra I 1st Semester Exam Review Classwork

Just a few reminders about graphing in slope-intercept form. Make sure both the slope and the y-int match the equation!

• Oh yeah!

• I already knew that!

• That is brand new information!

• Huh?

If you were solving a problem and the final answer was 2=2, how would you describe the solution?

• one

• no solutions

• infinite solutions

 $3y\ =\ 2g\left(x+h\right)\ \ solve\ for\ x$  

•  $x\ =\ \frac{3y+h}{2g}$  

•  $x\ =\ \frac{3y-h}{2g}$  

•  $x\ =\ \frac{3y}{2g}+h$  

•  $x\ =\ \frac{3y}{2g}-h$
