Slide 1
Linear Relationships and Equations
Understanding relationships between variables Graphing linear equations using y = mx + b format Slope represents rate o change Y-intercept shows starting value Example: A pizza costs $12 plus $2 per topping Equation: Cost = 2t + 12 (where t = number of toppings)
Slide 2
Ratios and Proportional Reasoning
A ratio compares two quantities using division Can be written as 3:4, 3/4, or '3 to 4' Equivalent ratios have the same value when simplified Proportions are equations showing two ratios are equal Use cross-multiplication to solve for unknown values
