Study Notes
Slope Formulas
- Slope formula for ordered pairs or a table: m = (y2 - y1) / (x2 - x1)
- Slope for graphs is determined by rise over run (rise/run).
Slope-Intercept Form
- The slope-intercept form of an equation is represented as y = mx + b.
- In this form, 'm' represents the slope of the line.
- The 'b' in the slope-intercept form indicates the y-intercept of the graph.
Helpful Tools
- Two essential tools for the STAAR exam are the Formula Chart and a Calculator.
- Desmos is a suggested calculator for use on assignments and during the STAAR exam.
Study Preparation
- Before taking a quiz, utilize notes, study guides, help videos, and calculators to prepare effectively.
Direct Variation
- The formula for direct variation is y = kx, where 'k' is a constant of proportionality.
Coordinates
- The coordinates for the origin are (0, 0).
