Systems of Equations Review & Intervention

Systems of Equations Review & Intervention

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

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

• The number multiplied by x represents (m) or the slope.

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