- Linear Interpolation
- is a method of estimating the coordinates of a point that lies between two given data points
- Positive Correlation
- Points on a scatter plot have a positive slope
- Standard Form
- Ax+by=c
- Fitting a line to data
- Find the begining of your data and then end of your data and find the slope and take a point to solve for it equation to make a best fitting line
- Slope-Intercept form
- y=mx+b
- Point-slope form
- y1-y2=m(x1-x2)
- Linear Extrapolation
- is a method of estimating the coordinates of a point that lies to the right or left of all of the given data points.
- Write a equation for: I have 3 dogs and every year i get 2 more
- y=2x+3
- Negative Correlation
- When the points on a scatter plot have a negative slope
- Writing an equation given two points
- 1. find slope 2 take slope and put it into this format y=mx+b then take one point and put them in for y and x to solve for b once you get b put it back into y=mx+b form and solve.
- Writing Equations of Perpendicular Ligns
- For one equation right it in with a reciprocal slope and slove
