Accelerated Algebra 1

1. Slope Formula

   • m=y2-y1/x2-x1
   • Used to find the slope between two ordered pairs. (x1,y1) and (x2,y2).
   • A Zero "underneath" means- undefined.
   • A Zero in the top means- 0

2. Standard Form

   • Ax+By=C
   • Also used to identify the equation of a line.
   • Be able to convert to y=mx+b in order to best match the equation to the graph.

3. Slope-Intercept form

   • y=mx+b
   • Used to identify the equation of a line.
   • m=slope b=y-intercept

4. Point-Slope Formula

   • Used to find the equation of a line given the slope (m) and the point (x1,y1) on the line.
   • **If given two points , Find the slope, then use the point-slope formula with either points to write the equation.

5. Direct Variation

   • y=kx
   • Check y/x for all ordered pairs.

6. Inverse Variation

   • y=k/x
   • Check yx for all ordered pairs.

7. Linear Regression

   • Done on the calculator
   • A method for finding the precise line of best fit givin a set of Data values.

8. Laws of Exponents

   • See Laws of exponents notes.

9. Properties

   • See properties notes.
