Work on the following problems to further gauge your understanding of Systems of Equations.

Slope Intercept Form

 $y=mx+b$  

• The number by itself represents (b) or the y-intercept.

• The number next to represents (m) or the slope.

• Make sure the equation is solve for y before determining the slope (m) and y-intercept (b).
